Ratepayers in a particular river scheme catchment pay a targeted rate that covers 80 per cent of the cost of managing that scheme. The remaining 20 per cent is covered by the general rate.
Regional council's asset management officer Kirsty Brown said council was looking for applicants to help in enabling effective communication and liaison between scheme ratepayers and the council.
"I'd like to acknowledge the work of the members of the previous liaison groups. These members have done a great job of speaking for their communities over the years. I am sure a number of these members will be happy to apply to join the new groups going forward.
"This new advisory group process sets us up with a terms of reference and a good outline of the work required for the coming three years. I look forward to seeing some quality applications come through," she said.
Ms Brown said this was an important role and nominees needed to demonstrate they met some or all of the appointment criteria set out under the terms of reference.
"Please look into those carefully before sending through an application," she said.
Interested scheme ratepayers can access the expression of interest, terms of reference, and criteria information on the website.
Submissions close next Friday.
