Noise complaints around Rotorua's eastern suburbs spiked overnight with 79 complaints received by the Rotorua Lakes Council.
Yesterday, just six complaints were received.
The council's independent acoustic expert took readings around the eastside industrial area overnight. In addition he placed a data logger into one of the hotspot areas and will analyse that data soon.
Of the 79 complaints, 10 each were received from residents living on Awatea Tce and Lynmore Ave.
Council staff were also out last night taking their own noise readings.
The council is to hold a public meeting on Wednesday, April 27, time and date to be advised.
To make a noise complaint call the council's dedicated line on (0800) 020 001, or email firstname.lastname@example.org.
