  • Rakaia-Selwyn Groundwater consent reviews
    the consent review proposes: - individual annual allocation limits, - the installation of flowmeters and dataloggers and in the case of larger takes, telemetry, - restrictions on all takes with direct hydraulic connection to surface water. An assessment is made as to whether a consent needs to be reviewed and a notice of review sent out accordingly. Proposed conditions follow and the consent-holder has time to respond with conditions of their own if they wish. In this case, a hearing with independent commissioners will be held and a decision made. Finally, there is an opportunity to appeal to the Environment Court.
