In a statement, NZ On Air confirmed a man who was a convicted paedophile was hired to work as a freelance cameraman on What Now in 2018 and again in 2019.
A NZ On Air spokesperson said Whitebait Media, which produces What Now, "vetted presenters, as the people who had the closest contact with children, but not the crew".
NZ On Air said Whitebait Media had "assured [NZ On Air] that they now routinely police vet all crew."
"We have only been made aware of this issue this week but believe the right action was taken by Whitebait Media in increasing police vetting. We think this should be an industry standard for sets where children are present and have raised it immediately with Screensafe."
Whitebait Media has not yet responded to requests for comment.

"Any school that has concerns about this person should notify police."
The company is owned by TV presenter Jason Gunn and his wife Janine Morrell-Gunn, and receives more than $3 million each year in NZ On Air funding.
Promoting health and safety in the screen sector, Screensafe executive officer Kelly Lucas said they were looking at their processes and would be working with NZ on Air to review what was in place.
"ScreenSafe follows the guidelines set out by WorkSafe, Police and the Ministry of Education but we are always reviewing best practice to ensure they are robust enough to recommend to the screen industry," she said.
