There are unconfirmed reports of flooding at Frazer Cove.
A Bay of Plenty Times reporter driving on Fraser Street said the roading between 13th and 15th Avenue is "very deep underwater".
"I can see a person standing on the side of the road gesturing to motorists to slow down, as cars are creating waves of water which appear to be going into nearby Phillips Garage."
Meanwhile, police are warning motorists in the Bay of Plenty to take extra care on the roads this evening.
"There is surface flooding in parts of Tauranga - this includes Cameron Road, Fraser Street, Eleventh Ave through to Fifteenth Ave, and to Greerton."
Roads are also affected in eastern parts of Rotorua, including Te Ngae Road.
