Rain causes surface flooding on the West Coast, one highway closed in Otago due to a slip


Road crews are monitoring conditions along the West Coast and the top of the South Island today, with some heavy but not unusual amounts of rain overnight on the West Coast.


SH6 has reopened on the Otago side.

There are minor slips being cleared and some surface flooding, says Waka Kotahi NZ Transport Agency Journey Manager Tresca Forrester. 

“Driving slower than the posted speed limit is advised, with your headlights on. 

“It takes longer to stop on slippery roads. Double the two-second rule to ensure a safe distance between you and the car in front,” she says. “If you don’t need to go out in hard rain conditions, stay put.” 


West Coast rainfall levels for the past 24 hours to 9 am today:

Westport 44mm
Sirdar Creek 135mm
Springs Junction 70mm
Inchbonnie 140mm
Greymouth 46mm
