A torrential downpour caused chaos in Napier yesterday, breaking seven straight days of sunshine in the Bay.
Driving conditions became hazardous and damage was caused to some of the inner city.
MetService said a combination of humid subtropical air and wind convergence triggered heavy showers and thunderstorms.
The heavy rain was a lingering effect from former tropical cyclone Victor, which is currently residing on the north-east of the North Island.
Meteorologist Stephen Glassey said Napier Airport received 21.2mm of rain between 10am and 11am yesterday.
"It was a pretty torrential and intense band of rain," he said.
Meeanee Quay was reduced to one lane due to surface water while emergency crews were called to Dickens St in Napier after reports of flooding.
The Fire Service was also called out to the AMI building in Hastings St just after 10 o'clock yesterday morning.
A blocked stormwater pipe meant water flooded out the basement of the building, and damaged an internal ceiling. The Fire Service spent an hour pumping out the water.
Police reported majority of the flooding had subsided shortly after 11.30am.
Black Caps fans will be keeping a close eye on the skies today.
The second one day international takes place at McLean Park with first ball to be bowled at 2pm and the forecast suggests a strong likelihood of a rain affected match.
However, Mr Glassey was confident plenty of cricket will be played with showers excepted to clear in the late afternoon.
"It's quite possible it will be delayed due to a wet outfield but there is a good chance the rain will clear come the afternoon."
Drizzle is expected to become heavier in the early part of the morning and to be accompanied by strong southerly winds.
This should ease before the scheduled start of play.
The Black Caps are currently 1-0 up in the three match series and if conditions allow, will look to seal the series in Napier today.
Conditions were expected to pick up slightly heading into the weekend.
Tomorrow will have periods of morning rain clearing in the afternoon and a high of 24C.
The weekend will again see periods of patchy morning rain although these are expected to clear in the afternoons.
The forecast high for the weekend is 25C.
