Wild weather including thunderstorms is set to put a dampener on the first weekend of alert level 3.
MetService expects heavy rain, cold temperatures and storms to hit much of the country come Sunday, after a fine few days.
"With a couple more days of fine weather ahead it's a good idea to clear any gutters or drains as many places will see a spell of heavy rain over the weekend," said meteorologist Lewis Ferris.
A severe weather forecast will likely be issued for the West Coast of the South Island with at least 100mm to fall at the weekend, with some areas looking to receive double or triple that.
Much of the country will receive a "healthy dose" of rain, with decent showers expected in central areas including Manawatu Northland and Auckland.
