A Government crackdown on the partners of welfare cheats could increase malicious complaints taken against people believed to be defrauding the system, the Opposition has warned.
The Labour Party supported the principle of eliminating welfare fraud but was concerned that it could penalise people who were unaware of their partner's fraudulent activity.
Social development spokeswoman Jacinda Ardern also highlighted that the removal of the need to inform beneficiaries that they were under investigation could lead to a more inefficient system which victimised people on Government support.
But she did not go as far as promising a repeal of the bill if Labour was elected.
