A short-lived scorching weekend will make way for heavy rain and gales this week.
On Saturday, many South Island centres hit temperatures in the mid-30s, and unofficially the mercury was closing in on 40 degrees in some sheltered areas.
Dunedin airport had a near-record high with a maximum of 34C, and yesterday it was Murchison's turn to reach 34C.
Metservice said an area of low pressure was moving away to the east, as a west to south-west flow spreads across the country.
It would bring stronger winds and gales to central parts of the country and exposed parts of Northland and Auckland, MetService spokesman Ramon Oosterkamp said.
