Other Aucklanders reported hail as far north as Waiwera.
Scattered heavy showers and thunderstorms were forecast to wreak havoc across Auckland, Great Barrier Island and the Coromandel Peninsula this afternoon.
Rain started bucketing down in Waitakere between 1pm and 2pm — accumulating 22.6mm, according to MetService.
MetService meteorologist April Clark said that soon eased off but "there is a lot of heavy rain around" wider Auckland.
What helps fuel those thunderstorms is a bit of heat at surface level, she said.
Earlier this morning waterspouts were reported in Auckland's Waitematā Harbour and the Hauraki Gulf as Waiheke Island was battered by a thunderstorm.
