Over the next 30 years, substantial growth is projected in both homes and jobs in the new future urban areas in Wainui, Silverdale and Dairy Flat. Part of Wainui has already been live zoned. Potential business land has been indicated in the Silverdale West area to the east of Dairy Flat Highway and on land around the airfield (for more information on this, see the Draft Silverdale West Dairy Flat Business Area Structure Plan).(external link)

The growth in these areas will mean that the population in this wider ‘north’ area will be more than four times the size of the current population of the Orewa-Silverdale area.


Since 2015, we’ve worked with Auckland Council to investigate a 30-year preferred transport network for North Auckland. This has needed to take account not only of population growth projections, but also when land will be ready for development according to the Future Urban Land Supply Strategy(external link).

In 2018, the programme reassessed the original network plans and investigated options for new or improved transport connections for North Auckland, including:


Auckland Council recently consulted on the draft Silverdale West Dairy Flat Industrial Area Structure Plan, and open days were held in April 2019.  The Supporting Growth team attended these events to answer questions on transport planning for this growth area. For further information about this structure plan, see Auckland Council's draft Silverdale West Dairy Flat Industrial Area Structure Plan(external link) webpage.

Route protection is a planning process that enables land to be protected for the future construction of necessary infrastructure such as transport. Route protection can be achieved by successfully applying for statutory approvals (designations) or by agreement with land owners. It provides certainty to landowners and developers about where essential infrastructure will be in the future. The programme’s aim is to protect all of the major strategic projects in our network in a staged way over the next few years.

The new strategic transport network plans are expected to be approved by the Auckland Transport and NZ Transport Agency boards by mid-2019. We will update property owners, stakeholders and the wider community about the networks, and begin a more detailed design phase as we move towards the preparation of detailed business cases.
