Labour says income levels have plummeted under the current Government with Maori and Pacific families the worst affected.
Data from Statistics New Zealand shows that average Maori incomes have fallen 11.5 percent, or 60 dollars a week since 2008.
The wages of Pacific Islanders have dropped by 19%, or $89 per week.
Labour deputy leader Annette King King says it is no wonder families are finding times tough.
She says the data makes a mockery of the Prime Minister saying people are better off under National.
Finance Minister Bill English says the drop in incomes is a result of higher Maori and Pacific unemployment due to the recession, caused by the previous Labour Government and the global financial crisis.
