Last year's bikini and beach trip might have to be exchanged for a jersey and a board game for this Christmas Day in Otago.
A low in the South Tasman Sea crosses south of New Zealand and extends a front towards Australia, which will cross the country on Christmas Eve and Christmas Day, bringing rain, followed by a few showers for Otago.
Temperatures are expected to be in the mid-teens, except for Queenstown and Wanaka, which might get into the early 20s the MetService says.
By Boxing Day, another ridge is expected to cover the country, bringing fine, sunny weather in most places, as the rain clears early in the day.
