TVNZ's director of content Jeff Latch has resigned ahead of a planned restructuring.
Latch will leave in July after 23 years at the broadcaster. He was appointed director of content in 2006 under then chief executive Rick Ellis.
In a statement, TVNZ chief executive Kevin Kenrick said: "At our heart we're a content business and Jeff's played a central role in TVNZ's business successes over many years. Our track record of sustained growth in TV audience share and OnDemand reach is testament to Jeff's leadership of our Content team - the one year birthday of DUKE's successful launch being the most recent example."
Latch said leading the content team had been an "enormous privilege".
"The strength of TVNZ has always been its people and I wish all those passionate, dedicated and talented individuals all the very best for the future," he said.
