The Rotorua Airshed boundary will be extended from tomorrow, June 3, to include future residential housing developments.
The Ministry for the Environment granted Bay of Plenty Regional Council's request for an extension of the airshed.
Council planning manager Julie Bevan said the airshed extension was a positive move towards protecting air quality in Rotorua.
"We really appreciate the community's significant efforts to improve air quality over the past 15 years.
"This airshed extension will help to protect Rotorua's air as the city continues to expand."
