Heavy rain and isolated thunderstorms are expected to move across parts of the country as the clock ticks to the weekend.
MetService has issued a number of heavy rain watches for the eastern parts of the North and South Island as a low-pressure system with associated fronts crawls down the east coast.
Great Barrier Island's heavy rain watch comes into effect at 6pm on Friday and is expected to end at 11pm Saturday.
Coromandel Peninsula will be under a heavy rain watch from 3pm Friday to midnight Saturday.
Gisborne, Tairawhiti's heavy rain watch comes into effect at 5am Saturday and ends at 11pm on Sunday night.
Bay of Plenty from Edgecumbe westwards will be under a heavy rain watch from 6pm Friday to 6am Sunday.
A heavy rain watch has been issued for Hawke's Bay from Eskdale southwards from 9am Saturday to 9pm Sunday.
Eastern Marlborough south of Ward's heavy rain watch comes into effect at 3am Sunday to 3am Monday.
MetService's website says there is still some "uncertainty" with the distribution and intensity of the heaviest rain.
"People are advised to keep up to date with the latest forecasts in case parts of these watches are upgraded to warnings or new areas are added."
MetService meterologist Ngaire Wotherspoon told Newshub the low pressure system was already bringing some heavy rain to Auckland on Friday afternoon.
"I'm sure if you're in Auckland you're feeling it."
In a tweet, MetService said a "few" lightning strikes have hit over the top of the North Island with some thunderstorm activity too.
Wotherspoon told Newshub the thunderstorms may bring some "intense bursts of rainfall".
