More information below.

9 September 2024

As part of work on the National Grid, Northpower will be using a helicopter to pull transmission wires across State Highway 1 (SH1) Waikato Expressway and Racecourse Road. 

This work means SH1 will be closed between the northern interchange (Cambridge Road) and SH1B interchange (Hautapu) on: 

• Saturday 14 September between 12pm and 4pm 

• Saturday 21 September between 12pm and 4pm 

Note: The work will not take longer than 4 hours. The road will open sooner if possible. 

Detours will be in place: 

• SH1 northbound: Exit at the Hautapu interchange, then north on SH1B, west at Bruntwood Road, left at Tauwhare Road before rejoining SH1 at the Tamahere interchange. This will add around 11 minutes to journeys.  

• SH1 southbound from SH1: Exit at SH26 interchange at Ruakura, turn south on SH1B and then rejoin SH1 at Hautapu interchange. This will add around 15 minutes to this journey. 

• SH1 southbound from Tamahere: Head north on SH1, exit at the SH26 interchange at Ruakura, turn south on SH1B and then rejoin SH1 at the Hautapu interchange. This will add around 22 minutes to this journey.  

This work is weather dependent. If it is delayed because of weather or other unforeseen issues, it will be carried out on Sunday 15 and 22 September. Mobile messaging boards along SH1 will be updated if these contingency days are needed.
