Farming land use consents
When do I need a consent?

Hinds/Hekeao Plains area only

You will need a consent if:

  • Your farm is not covered by an irrigation scheme that has a resource consent that manages nutrients, and;
  • If your farm is larger than 5 ha and your nitrogen loss calculation exceeds 15 kg/ha/yr.

Ashburton other than Hinds/Hekeao Plains Area

You will not need consent if:

  • You already have a farming land use consent; or
  • Your farm is part of an irrigation scheme that has a resource consent that manages nutrients; or
  • You have a water permit for irrigation, granted before 18 January 2014, with conditions that limit the amount of nitrogen that may be leached and requires the preparation of a plan to mitigate the effects of nutrient loss to water.

If none of these apply, then you will need a consent if:

Red Zone

  • Your farm has 50ha or more of authorised irrigation; or
  • After 13 February 2016, your irrigated area has increased by more than 10ha; or
  • You have an area of winter grazing* that exceeds the limits in the table below:
On a property Winter grazing
 Less than 100 ha  10ha or more
 Between 100 and 1000ha  10% of the property or more

 More than a 1000ha

 100ha or more

Orange and Green Zone

  • Your farm has 50ha or more of irrigation; or
  • You have an area of winter grazing* that exceeds the limits in the table below:
On a property Winter grazing
 Less than 100 ha  10ha or more
 Between 100 and 1000ha  10% of the property or more

 More than a 1000ha

 100ha or more

*Winter Grazing is the grazing of cattle within the period of 1 May to 30 September, where the cattle are contained for break-feeding of in-situ brassica and root vegetable forage crops or for consuming supplementary feed that has been brought onto the property.

Good management practices
Hinds good management and nitrogen loss rates
In accordance with Policy 13.4.15 in the Land and Water Regional Plan (LWRP), in the Hinds area (upper and lower) a farm's good management practice nitrogen loss rate is determined by:
  1. The type of farming activity; and
  2. The drainage characteristics of the soil; and
  3. The climatic conditions and topography of the property; and
  4. The type of irrigation system used (if any); and
  5. Whether the practices set out in Schedule 24a have been fully adopted.

This level of practice is applied to the farm's baseline land use (2009-13).

When is the good management practice nitrogen loss rate required to be met?
The good management practice nitrogen loss rate for a farm's baseline land use is to be met from 1 January 2017.
What is the threshold from which further reductions are required?
Further reductions for farms with a nitrogen loss greater than 20kgN/ha/yr in the Hinds Area are made from the good management practice nitrogen loss rate for a farm's baseline land use.
Why are the good management practice nitrogen loss rates for Hinds not the same as in Plan Change 5?
While Plan Change 5 (PC5) introduced a definition of the term “Good Management Practice” (GMP) it does not apply in the Hinds area. The architecture of the LWRP means sub-regional rules prevail over region-wide rules. The rules for the Hinds area (PC2) require compliance with Schedule 24a and the other factors in Policy 13.4.15 respectively, not compliance with the GMPs definition introduced by PC5.
The definition of “Good Management Practice” introduced by Plan Change 5 also has each word capitalised to indicate a difference, in PC2 the phrase is in lower case. The introductory text of the notified version of PC5 also stated submissions lodged on Plan Change 5 could not seek to amend the provisions in PC2. If the intent of Plan Change 5 had been to change the PC2 thresholds from which reductions were to be made, then the catchment load and percentage reductions would have been recalculated and changes made to the PC2 policies accordingly.
How is a good management practice nitrogen loss rate for baseline land use to be determined?
A Nitrogen Baseline (2009-13) OVERSEER® file for a farm is to be prepared. This will, however, need to reflect the minimum level of farm practices as contained in Policy 13.4.15.

This means the modelling of a farms nitrogen baseline needs to reflect the type of farming activity, the drainage characteristics of soil, climatic considerations and topography, the type of irrigation system used and the practices in Schedule 24a.

The information below outlines the minimum standard to be reflected in Nitrogen Baseline (2009-13) files and provides advice on how files can be adjusted to reflect the minimum.

Irrigation
Minimum
Schedule 24a states: irrigation application[1] needs to reflect use of soil moisture monitoring[2], a soil water budget, or an irrigation scheduling calculator. The data inputted into OVERSEER® will therefore need to reflect one of these irrigation management techniques while also reflecting the type of irrigation system used[3].

The minimum practice for irrigation management accepted by the Council is outlined here (PDF File, 245.42KB). This reflects an irrigation scheduling calculator approach with further refinements in accordance with Policies 4.65, 4.66, 11.4.15 and 13.4.15 to reflect:

  1. the monthly and annual amount of water required based on the irrigation system used; and
  2. the annual amount of water that was available as detailed in the relevant water permit(s).

Overseer file adjustment

As set out in the process for inputting irrigation management into Overseer (PDF File, 245.42KB)..

Fertiliser and Effluent Management - All Systems

Minimum

Schedule 24 states: Fertiliser is applied in accordance with the Code of Practice for Nutrient Management [2007]; and either:

(a) the Spreadmark Code of Practice [Feb 2014]; or
(b) With spreading equipment that is maintained and user-calibrated to Spreadmark Code of Practice [Feb 2014] standards.

Collected Animal Effluent:

(i) All collection, storage and treatment systems for animal effluent installed or replaced after 1 January 2014 meet the Dairy NZ Farm Dairy Effluent Design Standard and Code of Practice [2013].
(ii) The animal effluent disposal system application separation distances, depth, uniformity and intensity are self-checked annually in accordance with Section 4 ‘Land Application’ in the Dairy NZ guideline ‘A Farmer’s Guide To Managing Farm Dairy Effluent – A Good Practice Guide For Land Application Systems, Version 1 – Feb 2013’.

The minimum practice Fertiliser and Effluent Management accepted by the Council shall therefore reflect the practices above and relevant effluent consent conditions at the time.

[1] Clause b(iii).
[2] Soil moisture monitoring is defined in Schedule 24 as meaning “methods of monitoring soil moisture that uses volumetric or tension based methodology.
[3] Consistent with policies 11.4.15 and 13.4.13

Stock Exclusion

What’s prohibited?

Farmed cattle, deer or pigs having access to the bed of a river or drain where the following sites are mapped:
  • Īnanga spawning habitat and salmon spawning sites
  • Community drinking water protection zones
  • waterways 1000m upstream of a freshwater bathing site
  • the bed or banks of a spring-fed plains river

What kind of stock access requires a resource consent application?

A consent is required for any access by intensively farmed stock to any river or drain over 1m wide or 10cm deep or to a wetland. Intensively farmed stock are considered to be:

  • Cattle or deer grazed on irrigated land or contained for break-feeding of winter feed crops
  • Dairy cattle, of any class, including cows, whether dry or milking, and whether on irrigated land or not or
  • Farmed pigs.

What can be done without requiring a resource consent?

Conditions for permitted access

Other stock (not intensively farmed) are allowed to access rivers, drains and wetlands without consent if it does not result in:

  • Pugging or de-vegetation that exposes bare earth in the bed or banks
  • A conspicuous change in clarity or colour of the water outside the mixing zone
  • Cattle standing in any lake located within a lake zone, any lake classified as a high naturalness waterbody, or any lake located outside the Hill and High Country Area.

How is the bed of a braided river defined for stock exclusion?

A river is defined as a continually or intermittently flowing body of fresh water; and includes a stream and modified watercourse; but does not include any artificial watercourse (including an irrigation canal, water supply race, or canal for the supply of water for electricity power generation).

A braided river is a river that at some point in its length flows in multiple, mobile channels across a gravel floodplain. For the purposes of Environment Canterbury’s stock exclusion rules, the bed (including the banks) of a braided river is limited to the wetted channels, any gravel islands, the gravel margins, and the outer edge of any flood protection vegetation or where no flood protection vegetation exists, the lesser of:

  • The distance from the outer gravel margin to land that was cultivated or was in crop or pasture prior to 5 September 2015; or
  • 10m landward of the outer gravel margin as measured at any time, except that if a stopbank exists then the stopbank does not form part of the bed.

There is an exception to these conditions for stock crossing points (please contact Customer Services for more information)

Note: Within the Hinds zone, the bed of a lake, river or wetland also includes a drain, but does not include any sub-surface drain or drain that does not have water in it.

What is a wetland?

Wetlands are defined in the Canterbury Land and Water Regional Plan as coastal wetlands, wetlands which are part of a river, stream or lake; and natural ponds, swamps, marshes, fens, bogs, seeps, brackish areas, mountain wetlands, and other naturally wet areas that support an indigenous ecosystem of plants and animals specifically adapted to living in wet conditions and provide a habitat for wildlife. It excludes:

  • wet pasture or where water temporarily ponds after rainfall;
  • artificial wetlands used for wastewater or storm water treatment;
  • artificial farm dams, drainage canals and detention dams; and
  • reservoirs for firefighting, domestic or community water supply.

What is Wet Pasture?

The dictionary (Merriam-Webster) defines pasture as “plants (such as grass) grown for feeding especially of grazing animals / land or a plot used for grazing / the feeding of livestock”.

This definition links the purpose for which the grass is grown, with the feeding of grazing animals. This draws a distinction between grass that has been grown (introduced) for the purpose of feeding, to that which is not being grown but nevertheless, would be suitable for grazing animals to feed on.

Essentially, wet pasture is grass being grown for the purpose of feeding grazing animals.

The following factors, either individually or in combination, can be used as a starting point for on-site discussions:

  • Is the grass being actively grazed by farm animals?
  • Is the land being deliberately managed and actively maintained (includes fertiliser use, cultivation, mowing etc.) for the purpose of growing grass for grazing by farm animals?
  • Is there a predominance of exotic or introduced grass? (Pockets of wetland plant species may occur throughout areas of wet pasture and will need to be managed appropriately).
  • The grass has been (and is still being) actively maintained for grazing by farm animals since September 2015? (This is the operative date of the LWRP).
Silage Pits

What silage pits do not require a resource consent?

The use of a silage pit or stockpiling decaying matter such as composting, as long as:
  • the stockpile/pit is less than 20m3 volume
  • any liquid that drains from stockpile does not enter a surface water body
  • any decaying organic matter does not originate from an industrial or trade process.

Or, if larger than 20m3:

  • the stockpile is not within 50m of a surface water body, bore, property boundary, the Coastal Marine Area, or a Community Drinking-water Protection Zone
  • any liquid that drains from the stockpile does not enter a surface water body
  • the decaying organic matter doesn’t originate from an industrial or trade process

What silage pits need a resource consent?

A silage pit which cannot meet the conditions above will require a resource consent.

Note: These rules do not apply to bailed silage.

Offal Pits

What kind of offal pit requires a resource consent?

Any offal pit which cannot meet the conditions below.

What can be done without requiring a resource consent?
Conditions for permitted activity:

The pit is:

  • 50m3 or smaller
  • is designed to prevent surface runoff from entering the pit
  • is designed to prevent animals from entering the pit

And the pit must not be located:

  • within 100m of a surface water body, a bore used for water abstraction, the boundary of the site, or the Coastal Marine Area
  • within a Community Drinking-water Protection Zone as set out in Schedule 1
  • within the Christchurch Groundwater Protection Zone
  • onto or into land listed as an archaeological site
  • outside of a rural area

And:

  • The dead animals or animal parts were produced on the property
  • Must have at least 3m of soil or sand between the offal and the seasonal high water table
  • Only 1 pit per 100 hectares per year
  • When the pit is filled to within 0.5m of surface or no longer used, the contents must be covered with at least 0.5m of soil, or the pit is covered with an impermeable lid
  • The pit does not cause an offensive or objectionable odour beyond the boundary of the property
  • Offal not completely covered with impermeable material or soil is located more than 150m from any sensitive activity not located on the property i.e. homes, sports ground, churches, beaches.

Alternatively, where a dead animal cannot be disposed of in accordance with the above, the use of land to bury a single dead animal is permitted as long as:

  • the dead animal was produced on the property
  • the burial pit does not contain water, and the dead animal is immediately covered by enough soil or plant material to prevent odour or other nuisance
  • the burial site is at least 50m from any surface water body, bore or property boundary

Biodiversity Tool

There is a new prototype tool for on-farm biodiversity assessments.

Use the online tool to find out how biodiversity-friendly your farm actions are.

You can use the tool to:

  • assess the effectiveness of your current farm actions; and
  • explore the likely impact of changing those actions.

The tool includes 43 actions considered important for New Zealand farmland biodiversity management and reports on the impact for 10 biodiversity groups plus overall farmland biodiversity.

Responsibilities for water consent holders

Water taken from ground water and surface water sources enables our economy to thrive year-round. To ensure that water is used responsibly and that it continues to be a plentiful resource, consent holders have several responsibilities to be aware of.

Download the Irrigation responsibilities brochure (PDF File, 152.1KB) or read the information under the tabs below. 

Consent Responsibilities
Careful use of the water resource is something that Environment Canterbury takes very seriously. It is your responsibility to meet the terms of your consent.
You can do this by ensuring you supply your water data when it is due and by avoiding taking more water than is allowed under your resource consent (including taking water when rivers are on restriction).
What do I have to do?
As a consent holder, you are responsible for:
  • Compliance with all your consent conditions.
  • Ensuring all water takes over 5 litres per second have a verified water meter and data logger installed which is continuously recording actual daily water use.
  • Only taking water according to the specified volumes of your consent, including maximum flow rates, annual volumes and changes in permitted levels during periods of restriction.
  • Submitting actual water use data daily via telemetry, or annually by 31 July each year.
Monitoring your water use

Your water takes are monitored through automated systems as well as proactive desktop monitoring, and site inspections. During the irrigation season you’re likely to see Resource Management Officers out and about checking on water takes.

Minimum flow restrictions
Many resource consents contain a condition limiting the taking of water when a river or waterway is on restriction. As the consent holder, it is your responsibility to understand your minimum flow conditions by checking online.

If minimum flows have been reached, you must restrict your water take in accordance with your consent condition. You must also report any errors or any breaches that you observe.

Manual shut off?
If you have an irrigation device that requires a manual shut off, and a water restriction starts at midnight, you no longer have to get up at midnight to turn off your irrigator.

Instead, you can continue to irrigate until as late as 9am even though technically your water take is on restriction from midnight. This enables you to safely get out and turn off the device anytime between midnight and 9am.

If you choose to do this, then when the irrigation restriction ceases, you must not turn your irrigation on again until the time you turned it off.

For example, if you turned your device off at 6am on a restriction day, you must wait until 6am on a non-restriction day to turn it on.

Information on irrigation restrictions
Environment Canterbury’s website and customer service centre are the only places to find irrigation restriction information.

The Irrigation Restriction webpage contains up to date irrigation restrictions for your area, and relating to your consent (search for ‘irrigation’ at ecan.govt.nz).

This website is updated between 4pm and 7pm each day, with the restrictions being effective from 9am the following day.

You can also call Customer Services.

Fish screens
A fish screen is a structure intended to harmlessly divert fish away from water takes used for irrigation, stock-water, community supplies or hydro-electric power generation.

If you have a water take that requires a fish screen, you can find out more about their efficiency, and how they are monitored, on our website.

Weather - planning ahead
Plan your water use for the coming months by using NIWA’s useful Seasonal Climate Outlook. Careful planning can ensure that your water take doesn’t run out in the hot dry months.

To see the latest Seasonal Climate Outlook, go to NIWA.

Water use groups
Working with your neighbours year-round can provide benefits when water is restricted. As part of a water user group, consent holders can share water during times of restriction.

Members of water user groups each have existing consents to take water, and collectively manage the water resource allocated to them, during times of restriction.

Find out more about the Ashburton Water use group.

Backflow prevention
Many farmers use their irrigation systems for fertigation. If you do so, you must have a backflow preventer so that contaminants cannot enter the groundwater.

Your backflow preventer must be tested annually, and a copy of the test certificate sent to Environment Canterbury. Any backflow preventer which fails the test must be repaired or replaced and then re-tested.

Find out which backflow preventers are recommended, and read all about the requirements by searching for ‘backflow prevention’.
