If you are travelling around Canterbury roads are closed due to slips, flooding, bridge washouts. A civil defence state of emergency has been declared in areas and the army is assisting with evacuations and rescues.
Advise is to not travel.
If you have travel plans which include Canterbury in the next week it may be a good idea to delay or check roads.
SH to Akaroa is also now closed. Some of the bridge repairs and slips are not going to be a quick few day fix so some communities and areas are going to be isolated for a bit longer.
Porters bridge on porters pass on road to arthurs pass is one of the bridges which has had a washout so this road is also closed.
check the NZTA for latest road closures and info. I check it everyday before i travel always https://www.journeys.nzta.govt.nz/traffic
