Flooding update 6.20 pm: Buller River high – travellers advised to avoid Buller Gorge overnight


With rain steadily falling across the West Coast and Buller today, and the Buller River rising rapidly, the NZ Transport Agency is advising drivers to avoid the Buller Gorge overnight.

Both Murchison to Westport (SH6) or Reefton to Murchison (State highways 69 and 6) should be avoided, says Moira Whinham, Maintenance Contract Manager for the Transport Agency on the West Coast.

The Buller River has reached its alarm point at Te Kuha of 8.4 metres.

“At 8.8 metres the river floods the highway, and it is possible that the state highway will close overnight,” she says.

  • The alternate route to Nelson is via Reefton and Springs Junction (SH7 & SH65).
  • People can drive to Westport from Greymouth via the Coast Road, SH6.

Drivers are advised to check the Transport Agency’s website for up to date travel information before deciding to travel.

“People should keep away from the Buller Gorge overnight given the added risks of the dark,” says Moira Whinham.
