Human Rights Commissioner and former National MP Jackie Blue says it "it's never okay to touch someone without their permission."
Speaking after an Auckland waitress came forward to complain about Prime Minister John Key pulling on her pony-tail, Ms Blue said "there are no exceptions".
She said talking about what was - and was not - acceptable was a conversation worth having "and one every New Zealander needs to be a part of".
She also lent her support to a "Dear John..." open letter from the National Council of Women to Prime Minister John Key in the wake of revelations that he regularly pulled the pony-tail of a waitress at his local cafe in Parnell before being asked to stop.
He later apologized and gave her two bottles of wine.
