It is impossible without asking an OIA question to know exactly what that means in terms of percentage rise. That's because even though basic rates are known and constant, all the add-ons vary individually.
The last time the government published an average beneficiary payment was 2013:
An average sole parent with two children under thirteen, living in South Auckland would receive around $642 on benefit, including accommodation supplement and a minimal extra allowance for costs.As benefits are inflation proofed (though add-ons aren't) that would increase to $647.95 in the last quarter of 2015.
With today's increase she would be receiving $673 a week.
The best figure to compare that to is the average weekly incomes from wages and salaries:
Female Maori $723
Female Pacific $698
Either sex aged:
The table I am quoting doesn't provide gender breakdown with age but female rates are overall consistently lower than male.
So, all in all, for a young sole mother - particularly Maori or Pacific - $673 is looking fairly attractive.
Yes, the work-testing has been extended to part-time (20 hours) for mothers with youngest child aged 3.
But the work obligations are only ever useful in places where there are jobs.
It'll be interesting to observe the behavioural changes over the coming 2-3 years.
Remember that the early work-testing policy implemented to stop people adding children to an existing benefit has already failed.
