In July 2017 the New Zealand Government announced NZ$600 million (A$599 million) will be provided for a joint public-private infrastructure investment fund, Crown Infrastructure Partners, for new road and water infrastructure.

New urban areas in the north of Auckland, including Silverdale, Wainui and Dairy Flat have been identified by Auckland Council as areas where greenfield housing development can be significantly expanded over the next 30 years, provided the necessary infrastructure is in place to support the expansion.

The North project focuses on Wainui, where the existing infrastructure can only support the construction of 2,000 new houses in the area zoned for residential use in the Auckland Unitary Plan. It is estimated that an infrastructure investment of $201 million ($149 million for transport; $52 million for water) could sufficiently increase infrastructure capacity to service up to another 5,500 houses in Wainui.

The estimated $52 million infrastructure investment in the North would fund a number of water developments including the:

- New Wainui service reservoir ($15 million)
- New water supply booster pump station ($10 million)
- New Wainui sewer and pump station ($25 million)
- Wainui Storm water ($2 million)

The estimated $149 million infrastructure investment in the North would fund a number of arterial transport developments, including the:

- Wainui Arterial Road ($60 million)
- Curley Ave Bridge ($89 million)

The project is currently being assessed by Crown Infrastructure Partners.
