NZME's digital audio platform, iHeartRadio had almost 6 million podcast downloads in the August, reaching about 900,000 Kiwis.

NZME had eight out of the ten top podcasts in the country and was New Zealand's most popular podcast network.

NZME's chief radio officer Jason Winstanley said the company was enthusiastic about catering to both its traditional radio audiences and ensuring a strong digital presence for each network.

"We are continually innovating in this area and I'm proud of what our team is doing to continue to drive engagement and grow our audiences day by day," Winstanley said.

NZME chief executive officer Michael Boggs said having a strong radio network and constantly innovating across iHeartRadio means NZME continues to serve its valued audiences nationwide.

Boggs said NZME was committed to meeting the different listening needs of its audiences.

"It's phenomenal to think that NZME now reaches 3.6 million Kiwis across our radio, digital audio, print and online platforms, with nearly two million people reached via our radio platforms plus nearly 900,000 on our podcast network," he said.

The huge growth across iHeartRadio showed NZME was making major inroads to being New Zealand's leading audio company, Boggs added.
