I thought from memory that the US minimum wage was about $2.50 US with the exchange rate at I think around about 60 cents to the NZ dollar with the NZ minimum wage around about $13.50NZ (indeed many political groups and parties are calling for a $15 mimimum wage, I remember seeing the Workers Party and the Unite Group organising a petition around campus for this a couple of years back and became an official policy of the Mana party led by controversial far left MP Hone Hawerira possibly in an attempt to win more non-Maori Party votes and thus get an extra seat or two for his party in parliament under our MMP system) which from my very rough calculations in my head gave a minimum wage rate about 3 or 4 times that of the US although my calculations could be way out.
Minimum wage is $7.25; that's 8.69 NZD
