Broadcaster MediaWorks is exploring a potential merger with ASX-listed QMS Media's New Zealand outdoor advertising business.
QMS said it has signed a heads of agreement for the proposed merger which is subject to final binding terms and conditions.
The deal would create a new entity offering radio, television, digital and out-of-home advertising in New Zealand.
It is understood the new entity would be 60 per cent owned by MediaWork's hedge fund owner Oaktree and 40 per cent by QMS Australia.
QMS Media chairman Wayne Stevenson said: "New Zealand is important to our business and we are excited about the potential opportunity to create a leading multi-media group that will transform the New Zealand advertising business."
