The New Zealand Herald says Henry will leave the network at the end of the year, with Duncan Garner to take over the morning show.

A MediaWorks spokesperson told the Herald the reports were "all speculation" and would not comment further.

An internal email by Chief News Officer, Hal Crawford, said MediaWorks would not be commenting ahead of a new season launch on Thursday, but remained committed to the news.
