Justice Minister Judith Collins has introduced a new bill to Parliament to further combat organised crime and corruption.
Measures include requiring banks to report all international wire transfers of $1000 or more and all cash transactions of $10,000 or more to a financial intelligence unit in the police.
Police will also be able to share information with international counterparts.
People-trafficking offences will be broader so they apply to such activity in New Zealand, not just at the border.
Ms Collins said on Wednesday that New Zealand is regarded as one of the least corrupt countries in the world and it must remain vigilant.
"What we believe is that our legislation has fallen behind the times. This is quite a big bill, it's very much focused on money laundering."
