The Milford Road is set to be closed for a sixth straight day today, although there is a possibility it may reopen this afternoon.
The avalanche risk in the South has meant the road to Milford Sound/Piopiotahi has been closed since last Thursday.
NZ Transport Agency Milford Road alliance manager Kevin Thompson said State Highway 94 from the Hollyford Road to Milford Sound/Piopiotahi had been closed since last Thursday evening, snowfall having affecting travel before that.
"Currently, we have large, natural avalanches occurring in a number of places. Given the low cloud and continuing rainfall, which is triggering avalanche material from high up the slopes, we cannot safely get crews in to clear the road yet.
"It's been a large storm cycle over the past week or so. At the weekend we started getting heavy, warm rainfall on to our avalanche 'start zones', which triggered avalanches covering the road in places. These take time and machinery to clear once it is safe to do so."
