"While more snow is likely, the end is in sight. It's still a few days away, though," said MetService Weather Ambassador Bob McDavitt.
McDavitt said an anticyclone is expected to move onto the South Island on Friday, to cover much of the country by Sunday night.
"This is a cold cloudy high, so while showers in eastern areas will become steadily lighter from Wednesday onwards, they probably won't completely clear until the southerly winds die out in a few days' time.
For the next few days frosts will be severe in many places, and there is likely to be a lot of black ice on roads, McDavitt said.
