The Prime Minister's pulled out of his weekly TVNZ Breakfast interview - as a row escalates between the broadcaster and the National Party.

TVNZ says Chris Luxon's office informed them he'll no longer appear every Monday, and consider interviews case-by-case.

Luxon will continue to appear on Newstalk ZB and RNZ. 

Newstalk ZB senior political correspondent Barry Soper says the party's also laid out a complaint against TVNZ over the 'aggressive' conduct of the journalists.
