The NZ Transport Agency says State Highway 1 at Mercer is now fully open.
The Transport Agency continues to ask drivers to take care when driving through this area.
Motorists can find information about most road closures, detours and road works by calling the NZTA’s free phone on 0800 4HIGHWAYS (0800 44 44 49), which can also be used to report any significant road issues or hazards which people may come across during their travels.
The NZTA also uses other technology to provide information to enable drivers to make better informed choices about their travel. On The Move is a free service which enables people to sign up for information about crashes, road works and driving conditions on their frequently used routes - to sign up, go to www.onthemove.govt.nz(external link)
