Osborne said the best methods for boat anglers at the end of June would be harling close to the surface morning and evening, and trolling deeper during daylight hours when the day is brighter.
He said all Rotorua lakes were producing fish of outstanding quality including several fish in excess of 4kg weighed in on Lake Rotoiti recently.
Other popular spots about to close include the Ohau Channel and upper section of the Ngongotahā above State Highway 5, plus the Utuhina stream above Devon St, which will all close to fishing from the end of June.
Fish & Game staff will be out ranging to ensure the lakes and streams are "getting the rest they deserve", Osborne said.
