A suggestion the Gaurav Sharma situation could start to hurt Labour's image with voters.

Sharma has been suspended from the caucus after making multiple bullying allegations against the party.

Former Labour and United Future MP Peter Dunne says while Sharma may be exaggerating, he doesn't buy the idea there's no bullying in the party.

He told Mike Hosking if the Sharma drama continues, voters will start to take note.

Dunne says getting rid of Sharma doesn't match Labour's kindness image.
