The Kaimai Range also had its fair share of rain with 54.4mm of rain recorded during the same time period.
Between 20mm and 50mm of rain fell elsewhere across the Bay.
It was a wet day for much of the North Island on Sunday, with a broad slow-moving rain band bringing rain to all areas except Northland.
The wettest spots were recorded in the Bay of Plenty and Gisborne north of Tolaga Bay, with more than 100 mm of rainfall recorded in the ranges north of Gisborne in the 48 hours to midday Sunday.
"This slow-moving rain band is not expected to move much over the next couple of days, but should slowly weaken [Monday] and Tuesday," Flynn said.
"The wet weather just keeps coming in from the northeast, and this is what is causing the high rainfall accumulations we are seeing."
