The news brands reach 2.2 million Kiwis monthly while the sport and entertainment brands reach 1.1 million and 2.7 million Kiwis respectively.
"While APN NZ and The Radio Network will become NZME., our much-loved brands don't change," Ms Hastings said yesterday.
"The Wanganui Chronicle is still the Wanganui Chronicle, NewstalkZB is still NewstalkZB and the New Zealand Herald is still the New Zealand Herald. Only where you had previously seen 'APN NZ' or 'TRN' will you now see NZME."
She said the "me" in NZME. reflected that the company's brands and people were at the centre of what was going on.
"NZME. also recognises that New Zealanders want a New Zealand perspective. They want to be connected to the content they want, the way they want it and when they want it. That's what we give them.
"NZME. is uniquely positioned to deliver relevant and vertically integrated content. We can provide the innovation and solutions our advertisers need to connect with our audiences so they can better market their brands, products and services."
Subscribers to the NZ Herald and regional newspapers such as the Chronicle will continue to have their papers delivered and there will be no change to their billing at this time.
