Petone to Grenada Link Road (Wellington RoNS)

NZ Transport Agency (Waka Kotahi) · Wellington

A proposed ~6km four-lane Road of National Significance linking SH2 north of the Petone interchange to SH1 north of the Grenada interchange, with tunnels under Woodridge Drive and Mark Avenue and a connection into Petone at Hutt Road/Udy Street. Revived from the link road shelved in 2017. The NZTA Board approved the preferred (tunnelled) alignment and funding to seek route protection in October 2025; ground and environmental investigations and design run through 2026, with a substantive consent application expected late 2026. The preferred route would affect ~85 houses (up to ~200 properties potentially affected). Last formally costed at ~$1.8b (2018) and being re-estimated, likely higher; no construction funding is yet committed.

Election risk assessment

A revived Wellington Road of National Significance still at the route-protection / consenting stage with no construction funding committed. A National-government priority that Labour and the Greens would likely deprioritise, and the route is contested locally over property takings in the northern suburbs.

Government priority alignment

HIGH — Roads of National Significance four-laning — a core GPS 2024 economic-growth and resilience priority.
