NZX-listed NZME's share price fell by 16c or 24.2 per cent this morning after the Commerce Commission said it did not support the planned merger between NZME and Fairfax New Zealand.
At 50c a share, NZME's share price is now at its lowest point since listing in June.
NZME owns the NZ Herald, Herald on Sunday, nzherald.co.nz website, a range of regional newspapers, Newstalk ZB and a range of entertainment radio stations while Fairfax owns stuff.co.nz, the Sunday Star-Times and other metropolitan and regional newspapers.
Harper Asset Management portfolio manager Shane Solly said the decision was in keeping with the commission's recent "strident" announcements, having just poured cold water on the proposed Sky-Vodafone deal.
"I guess the Commerce Commission has made some reasonably strident decisions in a number of different cases, but this will surprise some investors," Solly said.
