More rain and wind is expected to blow through before a low in the Tasman Sea reaches NZ by Friday.

WeatherWatch.co.nz says between now and Friday, temperatures well above normal for this time of year due to the sub-tropical component.

"Thursday and Friday look wet and windy in a number of places," says a spokesperson for the weather organisation.

"We go into detail about latest rainfall figures - and of course, as always, refer to rainfall data in our new app or websites for your local estimates.

"The low falls apart by Saturday with a weak southerly change - but high pressure starts to return over Sunday and Monday from the west with a few showers and larger dry areas.

"We have your detailed New Zealand forecast through to Monday. Keep up to date with MetService official warnings."
