Local farmers, already facing waterlogged fields due to last week's heavy rainfall, are bracing themselves for more wet weather next week.
It comes as a blast of cold air blows through the Bay of Plenty.
Temperatures were expected to fall to -1C in Rotorua this morning, while in Tauranga temperatures were predicted to drop to 4C.
Forecasts for the start of next week warn Bay residents of another wet week ahead with continuous rainfall expected, but not before some sunshine over the weekend.
