Lots of illicit money is being hidden in New Zealand in lots of different ways.
A new report from police estimates $1.3 billion was laundered in New Zealand last year.
Money laundering expert Ron Pol says New Zealand offers lots of ways to easily hide bad money.
He told Mike Hosking one example is a strong real estate market, where foreign buyers can easily invest.
"For example, if you happened to be a methamphetamine dealer and you had a few million from that crime then purchasing real estate is a fantastic way of laundering those proceeds."
Authorities aren't even making a dent, with only about $14.4 million of $1.3b intercepted.
"That's a small number at 0.8 per cent, so the impact on criminals is not even a rounding error."
