TVNZ's Maiki Sherman's had her access to Parliament suspended for five days, after an altercation with an MP.
The decision comes after National complained to TVNZ, alleging Sherman aggressively banged on party whip Stuart Smith's office door for several minutes.
TVNZ says it has a different view of events.
Newstalk ZB's senior political correspondent Barry Soper the issue could lead to tighter rules for all reporters.
"I think what you'll find as a result of all this is that Speaker Gerry Brownlee, he'll be tightening the rules yet again and just explaining to the journalists that you don't chase MPs around Parliament."
The suspension's unrelated to claims Sherman lobbed a homophobic slur at another journalist at drinks in Nicola Willis' office last year.
