Every time a New Zealander wires more than $1000 overseas, it will be reported by their bank to police, if sweeping anti-corruption measures are passed into law.
Police will also be given power to share New Zealanders' names, fingerprints, criminal records and, in some cases, DNA samples to law enforcement authorities in other countries as part of a bill tabled by Justice Minister Judith Collins yesterday.
Ms Collins said the amendments would give more tools to crack down on serious crime and help New Zealand maintain its status as one of the least-corrupt countries in the world.
One of the key changes was to make all banks and financial institutions report to the police any international money transfers of more than $1000 or physical cash transactions of more than $10,000.
Officials estimated $1.5 billion in crime proceeds was moved around and out of New Zealand each year.
