New Zealand on Air says it will not give any more funding to National MP Melissa Lee's production company, until she repays $80,000 of taxpayers' money.
The broadcasting agency has written to Lee, saying her company, which produces TVNZ's Asia Downunder, has broken the rules, and needs to pay back the money.
Broadcasting Minister Jonathan Coleman says he knew about the issue in August, but thought it "didn't sound like a big deal".
