New census data shows the income gap between Auckland's poorest and richest suburbs has grown over the past seven years.
It shows while people's wages in some areas have risen over the past seven years, other areas have seen a significant drop in income.
In 2006, the median income for someone in the Orakei area, including Mission Bay and St Heliers, was $36,600.
Data from last year's census, which has just been released, shows that figure has grown to $42,700.
But incomes for those in the poorest suburb of Mangere-Otahuhu actually fell, dropping $200 to $19,700 last year.
The figures for Auckland as a whole show the median income last year was $29,600, an increase of nearly $3000 from 2006.
A Salvation Army spokesperson is calling for a review of income support after release of the data.
Social policy analyst for the Salvation Army, Alan Johnson, says he thinks the gap is the result of an ageing population and income support policy.
He says a review is needed as the Government's welfare changes haven't addressed the problem.
