Petone to Grenada Still at Referral Stage as Fast-Track Decision Waits
No decision has been made on the Petone to Grenada highway's bid to use the fast-track process, the NZ Transport Agency says.
The Agency confirmed the position on 29 September 2026, in response to RNZ questions about the project under the fast-track regime RNZ. The proposal is at the referral stage. No referral has been granted. No full fast-track application has been lodged.
Think of referral as the first gate. Under the Fast-track Approvals Act, a project must show it is eligible and finish pre-application work before ministers can refer it into the fast-track consenting track. At this stage, comments are sought from people including the relevant local councils.
The Agency also said Petone to Grenada remains on the Government's Roads of National Significance programme, with further phases subject to future funding decisions. The listing stands. Whether it is built, and when, depends on later Budget and National Land Transport Fund decisions. The Fund is the main central pot for roads, paid for largely through fuel tax and road user charges.
The timing has changed. The Agency had aimed to apply for fast-track approval by the end of 2025. In July, Transport and Infrastructure Minister Chris Bishop said the project had applied for fast-track approval. Around the same time, it was listed among "longer term" road projects. That matched RNZ reporting that the Petone to Grenada Link Road, known as P2G, had been put in the slow lane with no set date RNZ.
Local debate followed that process. In January, Wellington's northern suburbs called for a say on the project RNZ. In March, residents near the Lower Hutt end spoke about uncertainty while the referral was pending. The Act allows for council input before ministers decide on referral, not only at the later consent stage.
P2G is one of three road projects described in October 2025 as working through fast-track approval applications. The others were Mill Road Stage 1 in Auckland and the Belfast to Pegasus and Woodend Bypass in Canterbury. They are in different regions. The common point is use of the referral path to test eligibility early.
Investigation work is continuing. The Agency, also called NZTA Waka Kotahi, says ground and environmental studies are underway to inform design and planning, and it is preparing its planning application under the Fast-Track Approvals Act. In January, the Agency said that work would run through to March 2026.
The fast-track portal already holds documents that mention the corridor. They include a Belmont Quarry Development recreation report described as an impact assessment for the Petone to Grenada project, and a Takitimu North Link Stage 2 Economic Benefits Report that refers to a Grenada Petone Link Economic Assessment used as evidence in Environment Court proceedings. A separate Technical Report 11 on Freshwater and Wetland Ecology lists Petone to Grenada alongside other projects including Northland Corridor (Ara Tūhono), State Highway 25A and Hawkes Bay Expressway.
The broader context here is sequencing rather than cancellation. Ministers have kept P2G in the Roads of National Significance group while directing near-term spending to other roads. NZTA has kept consenting work going through investigations and a live but undecided referral. For councils, iwi, submitters and contractors, the practical questions are when ministers will decide on referral, what scope any referred project would cover, and which future funding round would allow a consented corridor to move to procurement and construction.
