It can be instructive to check the Horowhenua District Council LGOIMA Responses page from time to time. LGOIMA stands for Local Government Official Information and Meetings Act.
Back in November 2023 a requester asked numerous questions about vehicle access to Waikawa Beach, including several about resource consents. Some responses (PDF, Reference Number: 2023/1018) didn’t really bring any new information, but one question and answer were interesting:
“How much has been spent on “river training” to date including the cost of applying for a resource consent to do “river training”?”
Records indicate that $54,628.20 has been spent by HDC on various aspects of physical work related to the management of Waikawa Stream since 2000.
One follow-up question that could have been asked was whether any contributions from other sources were made towards river training costs. It’s possible, for example, that Horizons Regional Council also contributed funding.
