The Queenstown Lakes District Council said crews worked to clear the road linking Queenstown and Wanaka.
A spokesman said the road was open again by 9.45am.
MetService advised earlier this morning that rain had turned to snow about the top of the Crown Range. Between 8am and 11am, up to 3cm of snow was forecast to accumulate about the summit, with lesser amounts lower down.
It lifted the snow warning just after 11am, saying the road was not affected now.
Meanwhile, rock scaling work that began on Monday further down the Wanaka side from the summit is continuing as normal, and road users should expect delays between 8.30am and 4.30pm this week.

Further south, part of State Highway 6 is affected by surface flooding.
Waka Kotahi/ NZ Transport Agency advised at 10.30am today that there was a 30kmh speed restriction at Kingston, north of the Allendale Road intersection.
Road users should take extra care when travelling through the area.
