Wellington City Council has asked the company behind a new wind farm at Makara to report on noise issues after receiving more than 750 complaints.
Meridian Energy's Project West Wind, which opened in April last year, has 62 turbines in the area around the settlement.
Compliants lodged by residents with the council include loud bangs and disturbance of sleep caused by a low-pitched hum.
The council says it has no evidence Meridian is breaching its resource consents, but is seeking to have the noise reduced.
Meridian Energy says it is confident it can reduce the noise problems with the help of the turbine manufacturers, Siemens.
