Bromwich captained New Zealand in the Anzac Test loss to Australia on Friday night.

Kidwell said he was "gutted" when he heard the news.

"They have broken my trust, their teammates' trust and the New Zealand public," he said.

NRL chief executive Todd Greenberg approved of Melbourne's two-game ban for Jesse Bromwich while Kiwi teammate Kevin Proctor is yet to be sanctioned by the Titans.

The pair were filmed consuming what is thought to be an illegal substance in the early hours of Saturday.

Proctor has stepped down from playing duties for the Titans and relinquished his captaincy

"Both clubs spoke to our Integrity Unit over the weekend about the parameters of those decisions. Ultimately they're decisions for the clubs," Greenberg told reporters on Monday.

"But we were comfortable with that."

A Canberra man is facing charges for supplying the players.
