New Zealand set to scorch again - and now the rain's here too

New Zealand is set to scorch again this week, as the hot weather continues.

On Wednesday, temperatures in several cities around the country peaked at over 30degC.

The heat is set to continue on Thursday, with Alexandra forecast to get to 32degC, Wanaka and Masterton to 30degC and Taupo and Hamilton to 27degC.

"It's been a warm week - pretty much right across New Zealand - with many spots climbing towards 30degC and there are some more hot days in store," MetService says.

"Warm temps and humidity remains over much of NZ for the next couple of days. Only the west and far south of the South Island fall below 20degC on Sunday as a series of fronts turn the flow southwest."

A map of the temperatures around the country shows nearly the whole country getting burned. Only the Southern Alps escapes the heat.

There is a chance that the increased moisture in the air will lead to periods of heavy rain around the South Island, starting on Friday.

The showers will then move up the country and hit the North Island on Sunday. However MetService says the high that is causing the warm weather is likely to stick around - adding humidity to the heat.
