NZME and partner radio stations have dominated Auckland in the latest survey, with more listeners and a greater market share than rival MediaWorks.
Newstalk ZB continued its prominence as New Zealand's number one commercial radio station with Mike Hosking's show smashing the competition across the country and in Auckland. The station extended its lead in both Auckland and Wellington - and grew its audience to 513,000 nationally.
"Our lead in Auckland continues to increase and is wonderful testament to the work and passion of our broadcasters, producers and journalists," said NZME managing editor Shayne Currie.
"Mike Hosking continues to reign supreme at Breakfast, following a period of hard-hitting and agenda-setting interviews and news stories."
NZME's combined newsroom - which includes NewstalkZB, Radio Sport, The New Zealand Herald, Northern Advocate, Bay of Plenty Times, Rotorua Daily Post, Hawke's Bay Today and Whanganui Chronicle - was paying dividends, Currie said.
