"These are not people being kicked to the curb ? they are people who are working, and earning enough money that they are no longer eligible for the benefit, who have failed in their obligation to tell us."
There have been 351 successful prosecutions, with a further 435 underway. Of the $56.3 million that has been overpaid, $3.1 million has been recovered.
Under the new 'low trust client' system, there are 1884 beneficiaries who have been previously been dishonest and are now subject to strict monitoring. No subsequent offending has been detected by those under watch.
In 2013/14, there were also 329 successful prosecutions for relationship fraud, totalling overpayments of $15.4 million. This fraud is most commonly committed when a person pretends they are not in a relationship so they can still receive a sole parent benefit.
A law change in April means that both parties to the fraud are now liable, which is expected to apply to 700 to 1000 cases a year.
The ministry is testing follow-up interventions with sole parent beneficiaries to ensure they are getting correct entitlements. Results are due later this year.
"While it's still early days I'm very encouraged by what we're hearing from our staff as to the success of these preventative measures," Mr Borrows said.
He said the welfare initiatives in total had seen 4614 completed investigations, established 2270 overpayments, and prosecuted 893 people during the 2013/14 year.
In total, $88.4 million of fraud and illegitimate overpayments were established.
"When someone commits benefit fraud everyone loses ? the taxpayer and the beneficiary. The best result is if we can help people understand their options and their obligations before they end up receiving money they're not entitled to."
