A heavy rain watch is in force for the Canterbury Plains and foothills between the Rangitata River and Amberley until 10am.
Meanwhile, further south, a heavy rain watch is in force for Dunedin east of Pukerangi until 7pm.
Burrows said today had the potential to be Dunedin’s wettest day of the year so far.
“It hasn’t seen that much rain this year yet and it’s been fairly dry.”
Burrows said the low, which had been bringing extreme weather to New Zealand over the past few days, would track off to the southeast.
“As it does, it is going to help ease that rain from the eastern areas of the South Island.”
Meanwhile, the North Island is forecast to only experience cloudy periods with occasional showers.
The weather conditions will continue to improve across most of New Zealand tomorrow.
Strong winds created chaos on Sunday night, bringing trees down on houses and blocking roads across the lower North Island.
More than 30,000 properties were also thrown into darkness thanks to power outages.
“People will be pleased to hear [that] across the country, we will see plenty of sunny spells,” Burrows said.
“There will be some showers throughout the afternoon, but it’s going to be largely a nice day for the country.
“Winds are looking fairly light as well.”
Temperatures were currently close to or below average for this time of year, Burrows said.
“As we head into Wednesday, they’re heading into more normal temperatures for this time of year.”
