Despite relatively high average annual rainfall overall in Northland, a lack of storage means much of this water can’t be harvested for use at other times, including summer and during droughts in the Kaipara and/or mid-North areas.
A series of studies looking at water storage options aimed at addressing water use - and the potential economic benefits to the region - has progressed in stages over the past five years. These studies are mainly focussed on commercial supply but could have a part to play in municipal supply.
The initial studies were funded from Northland Regional Council (NRC) through its Investment and Growth Reserve, Ministry for Primary Industries (MPI) and Crown Irrigation Investment Limited (CIIL), and support from Northland Inc (NInc).
In May 2019, the project received additional funding of $18.5M from the Provincial Growth Fund (PGF) fund to help further investigate and, if feasible, begin construction of community-scale water storage and use options in the Kaipara and/or mid-North areas.
This pre-feasibility phase will focus on the three catchments identified in earlier studies.
Identified Kaipara water use command area and potential water source
Identified Mid-North A water use command area and potential water source
Identified Mid-North B water use command area and potential water source
