A number of South Island towns, including Westport and Nelson, are currently isolated due to state highway closures caused by high river levels, flooding, fallen trees and slips.

Other isolated towns include Tākaka, Collingwood and Murchison in Tasman District.

“Hanmer Springs in Canterbury currently has no access from the state highway to the south, however that is expected to be resolved by midday today with crews clearing slips now,” says Tresca Forrester, Journey Manager for Waka Kotahi NZ Transport Agency.

People need to check the Waka Kotahi NZ Transport Agency map before setting out if their journey is essential.

Ms Forrester says people should avoid driving in these areas today, particularly given more rain is falling in Nelson and Marlborough and more roads may well close as river levels and rain peaks later.

“Our crews are working as hard as they can but these slips and debris will take time to clean up and flood waters take time to subside. In some places we have to wait until the river levels have subsided to get access to the slips. Please do not drive if you do not have to or delay your journey until later today and check highways then.”
