High pressure is to the south-west of NZ, low pressure to the north-east – this creates a colder southerly quarter flow into NZ off and on across this coming week. This means frosts, widespread for the first time in 2024, will fan out across a number of sheltered South Island areas and then spreads further into the North Island by Friday (although not as widespread in the north).

A couple of weak cold fronts this week will bring showers to the south and east of both main islands and a dusting of snow on the ranges.

Meanwhile a low with tropical connections deepens and grows east of NZ and will help create a south-easterly flow for much of the North Island and that will drag in some showers to Gisborne and East Cape areas.
