Following on the for the scoping study, council, in close co-operation with the Kaipara District Council and the Far North District Council and with funding assistance from the Provincial Growth Fund (PGF), undertook a pre-feasibility investigation. The objective of the pre-feasibility phase was to assess whether there are viable water storage and distribution scheme options based on a series of small-scale reservoirs near Kaikohe in the Mid-North and on the northern Pouto peninsular, south of Dargaville, that provide a reliable water source to support high-value land use and which meet the PGF investment principles for water storage (Water Principles).
The pre-feasibility phase was governed by a Project Steering Group (consisting of the Chief Executive Officers from the Northland Regional Council, Far North District Council and the Kaipara District Council, and two Crown appointed representatives) and a Project Advisory Group (made up of invited representatives from iwi and hapu, Lake Ōmāpere Trust, landowners, primary industry sectors, environmental agencies and the community).
The overall conclusion of the pre-feasibility assessment was that a viable scheme option exists in both areas, and that the preferred options will consist of multiple water storage sites connected through a distribution system rather than based on one or two large reservoirs.
The detailed findings of the pre-feasibility phase are contained in the following four reports. It has been necessary to withhold some of the content in these reports under section 7 of the Local Government Official Information and Meetings Act 1987.
