$13.50 an hour is $385 a week after tax.
That's what single mum Emma Endemann earns after tax each week as a cleaner on the minimum wage, to support her three schoolchildren.
It's not enough to make ends meet so Emma’s son Peniata goes to work every day after school to bring home more money for school uniforms, clothing and extras.
As a comparison, in Australia the minimum wage is $15.51 Australian dollars - or more than NZ$20. Here it's $13.50.
So tomorrow the Service and Food Workers' Union launches a campaign for all New Zealanders to be paid a "living wage" rather than a minimum wage. The union says a living wage should allow workers to earn a decent wage to avoid the stress of poverty.
Over the next three nights Campbell Live will meet three families surviving on the minimum wage.
Watch Lachlan Forsyth’s report on the Endemann family.
