No more NZ stories on 60 Minutes

60 Minutes' Belinda Henley with director James Cameron.

New Zealand's oldest current affairs series will no longer feature local investigations and in-depth stories as 60 Minutes undergoes a major restructure.

Executive producer Belinda Henley and line-producer Terri Cavanagh are both leaving the programme as a result of the move, which will see it feature international content from now on.

Posting on Facebook, Henley wrote: "After 126 episodes it's time for me to say goodbye to 60 Minutes. It's been an incredible three years, fulfilling a lifetime ambition to work on the world's best current affairs show. I've met inspiration people, helped tell some wonderful stories and gave me the ultimate friend and work wife Terri Cavanagh."

A Prime spokesperson confirmed the pair are leaving, as the result of an internal restructure.

"60 Minutes will continue to showcase current affairs content from around the globe including Australia and the US. There are no current plans for in-depth investigative local stories but topical New Zealand content will be highlighted in the programme."

By comparison, this Monday's season finale will feature two locally-produced stories, including a Carly Flynn interview with Pete Evans and the story of the Waikato siblings behind Zuru Toys.

The move mirrors a similar decision made by TVNZ last year, which saw the network drop all local content from its 20/20 series. Instead, a New Zealand presenter introduces international stories.

60 Minutes first began screening in New Zealand in 1990 on TV3, before moving to TV One in 1993. Eight years later, it returned to TV3, where it stayed for 10 years, before moving to Prime.

Several of 60 Minutes original team members remained at TV3 and worked on 3D, which was recently cancelled.

Earlier this week, Maori Television confirmed major changes to its award-winning series Native Affairs, which will be cut down to a half-hour format.
