It would turn "very wet" on Monday with a low-pressure system moving over the North Island - set to bring widespread and possibly heavy rain and strong wind to the region. This weather would likely continue on Tuesday, he said.
He urged people to keep a "pretty close eye" on severe weather watches and warnings.
The weather would ease on Wednesday but it was likely some showers would continue for the second half of the week, he said.
He also said temperatures next week would likely be muggy and "relatively warm" as the air was coming from warm waters north of New Zealand.

Staying well these school holidays
Bay of Plenty District Health Board's chief medical officer Dr Luke Bradford said children should rest, play and reconnect with whānau these school holidays. Resting was particularly important for those who had been hit hard with winter illness recently, he said.
He anticipated the school holidays would act as a circuit breaker for the circulation of seasonal flu, colds and Covid.
"The fact they are not going to be in the classrooms for the next two weeks we are hoping will slow the spread of these viruses."
Those who hadn't already should also get vaccinated against Covid-19 and influenza.
He also encouraged those travelling on public transport and part of big indoor activities to practise mask-wearing - but acknowledged this could also be a struggle for young children.
He said in general there had been a "definite shift in the public mood around mask-wearing", and urged people to practise masking, keep a safe distance and maintain good hand hygiene as an act of public service.
In a social media post, Unite Against Covid-19 urged families travelling these school holidays to make sure they had a plan in place in case they become infected with Covid, or become a household contact.
Some of these tips included:
• Plan how to get home safely to isolate — you can only return home if you can drive there, you cannot use public transport, ferries, or fly. • Talk through the plan with your travelling companions. • If you cannot drive home, it is likely you will need to stay where you are for your isolation period • If you get cold, flu or Covid symptoms while away from home, get tested immediately. Do not wait until you get home.
