North Island state highway network update


Waka Kotahi NZ Transport Agency contractors have been working to re-open access across the motu today, although wet weather is set to continue and a number of state highways remain closed.

State Highway closures as of 5pm:

Northland region

SH1 Brynderwyn to Waipu:

  • Forecast wet weather means that SH1 Brynderwyn Hills will remain closed from the SH12 intersection to Waipu.
  • Motorists should expect delays with a detour via Waipu / Mangawhai. Freight and heavy vehicles are advised to detour via SH12.
