There are greater odds of this being true for the northern regions of the North Island, which has a 50 per cent chance of warmer than average weather this winter, compared with 40 per cent for the rest of the country.

However, it isn't all good news, as NIWA predicts there will also be a high chance of cold snaps in June and July.
