And there'll be more rain for the city as the week goes on, with MetService saying Aucklanders should expect heavier showers to hit midweek, from Tuesday to Thursday.
"Sunday marks the change to a more active weather regime for NZ," a MetService spokesman said.
"The unsettled conditions look to last beyond midweek but current information point toward a more relaxed situation by the weekend."
And it's not just the City of Sails with a grey and depressing weather outlook.
Northland and the Coromandel can expect cloud increasing today with showers developing during the afternoon and evening.
Thunderstorms are also possible.
Increasing cloud will also hit Gisborne with light rain developing late in the day.
MetService say that from Waikato to Wellington, including Bay of Plenty and the central high country there will be cloud increasing during the morning and periods of rain from afternoon, with heavy falls and possible thunderstorms especially in the west.
The same goes for Hawke's Bay, Wairarapa, Marlborough and Nelson.
Further down the Mainland, Cantabrians are in for a rain and thunderstorms in high country areas and brief falls elsewhere.
For Buller, Westland and Fiordland, Otago and Southland - similar periods of rain or showers, sometimes heavy, with squally thunderstorms and hail.
And in the Chatham Islands there will be "occasional drizzle".
