The Pacific Island leaders have arrived on Waiheke vineyard for their annual retreat - but some leaders were not happy with the choice of "silly shirt."
The Pacific Islands Forum leaders uniform was a black Icebreaker jacket - with a silver fern on the chest in a sly show of support for the All Blacks.
It was dubbed a practical measure to keep leaders accustomed to more tropical climes warm.
However some were not so comfortable with the choice - notably Samoan PM Tuilaepa,
Tonga's PM Lord Tu'ivakano and Australia's PM Julia Gillard - the three countries with teams in the Rugby World Cup.
Mr Key joked he would make it compulsory for the first game tomorrow and had also given them All Blacks jerseys to wear.
