Boozy behaviour by New Zealand sailors abroad is "not a good look" for the country and must be addressed, says Labour Party leader Phil Goff.
The Opposition leader has called for action after reports of drunken sailors shirtless and brawling in the main street of Port Vila during an April stopover.
The reports surfaced days after it was revealed that HMNZS Te Mana skipper John Butcher was relieved of his command, allegedly over rapidly downing several glasses of wine at a formal function in Vanuatu last month.
Speaking of the April incident, Mr Goff told the Herald he could recall nothing similar during his tenure as Defence Minister between 2005 and 2008.
"Our Defence Force are our ambassadors internationally and they're generally excellent for us, but we've got to take this sort of behaviour seriously. It's very clear that whatever the factors are, it's not a good look. The navy and the Defence Force has to address this."
