SH20B will be upgraded to provide additional lanes in each direction, dedicated to bus and high-occupancy vehicles between Pukaki Creek Bridge and SH20 to allow new 10-12 minute bus services between the airport and Puhinui Station Interchange.
Other early improvements on SH20B to be delivered by 2021 include:
- Safety improvements including median barrier protection and improved lighting.
- Walking and cycling facilities, pavement improvements drainage and stormwater treatment.
- Two new intersections – at Campana Road to allow for future development south of the state highway, and at Manukau Memorial Gardens to improve safety.
Walking and cycling opportunities along SH20B will be improved with a dedicated shared path that connects with walking and cycling facilities on Puhinui Road. The shared use path will run on the north side between SH20 and Manukau Memorial Gardens, to provide access to the gardens, cross at the signalised intersection, and travel on the south side along SH20B to improve access to the future developments.
New pedestrian and cycling facilities will be added alongside the existing bridge over Waokauri Creek to allow for a continuous separated facility. The path will be easy to access, well-lit at night and have improved wayfinding and line marking, making it safe and easy for users of all ages and abilities.

Speed limit review
There are three different speed limits along a 3km section of state Highway 20B – 50km/h, 60km/h and 100km/h.
We are looking at introducing a consistent and reduced speed limit to recognise the change in the road environment and in 2021, once construction on the early improvements is complete.
In the last five years, 22 collisions have been recorded on State Highway 20B, two of them overtaking/head on crashes. SH20B is predominantly rural environment but significant development is planned.
We think reducing the current 100km/h speed limit to 60km/h between Manukau Memorial Gardens and Pukaki Creek, will provide a safer and consistent speed limit for the corridor.
We want to know what you think about the current and proposed speed limit. We will use your feedback to recommend a new speed limit and then formally consult with key stakeholders and the community early next year.
