Stormy weather is expected to continue in the upper North Island this week.
A heavy rain warning has been issued for Rotorua and the Bay of Plenty, along with a severe weather watch north of the Hawkes Bay.
"A deepening low is expected to move southeastwards across the North Island, bringing a burst of heavy rain during Wednesday," the MetService said this morning.
Northland, Auckland, Waikato, the Coromandel Peninsula, Gisborne and Hawkes Bay are affected by the watch.
Stormy conditions also hit Auckland yesterday. The Fire Service went to half a dozen weather-related incidents yesterday morning. Power was cut in Titirangi, Greenhithe, Coatesville and Okura but largely restored by early evening.
In Titirangi, a tree fell on a power line, cutting power to about 900 homes.
Up to 90mm of rain is expected in the Bay of Plenty and Rotorua from noon today until midnight tomorrow.
Slips and surface flooding are possible, the MetService warned, and hazardous driving conditions are expected.
The weather service is forecasting heavy rain of at least 15-25mm during "thundery downpours".
The severe weather watch was also issued for "a burst of heavy rain" from Northland to Hawkes Bay.
