Project introduction

Waka Kotahi NZ Transport Agency is seeking public input into proposals to set permanent new speed limits on State Highway 1 Waikato Expressway, between Hampton Downs and Tamahere.

Consultation for this speed review closed on Tuesday 23 November. We are reviewing the submissions we have received and will provide a summary of feedback and our decision on any permanent speed limit changes within the coming months.

Thank you to those who have made a submission.

What we know

The Waikato Expressway is a key strategic transport corridor for the Waikato region, connecting Auckland to the agricultural and business centres of the central North Island. It will improve economic growth and productivity through safer, more efficient movement of people and freight.

The Government invests heavily in our transport system and has upgraded many state highways with a focus on making them safer and more efficient.

When completed, the Waikato Expressway will improve safety, reliability and reduce travel times and congestion on State Highway 1 by delivering a four-lane highway from the Bombay Hills to south of Cambridge.

Some of the more recently completed sections of the Waikato Expressway are built to very high safety standards. Because these roads have features that make it safer for travelling at higher speeds, the speed limit may be set to a higher limit than other state highways.

In late 2017, following consultation, the speed limit on the Cambridge section of the Waikato Expressway was increased to 110km/h.

The Huntly, Longswamp and Rangiriri sections of the Waikato Expressway have been designed and built to be safely operated at 110km/h.

The Hamilton section, which is due to open in 2022, will also able to be safely operated at 110km/h.

Waka Kotahi is now preparing to upgrade the remaining sections so when finished, from Hampton Downs to south of Cambridge, the Waikato Expressway will meet the necessary design and safety standards for a 110km/h speed limit.
