Six people have been arrested over a $1.6 million invoice scam which involved the sale of advertising in magazines that did not exist or were not as widely circulated as claimed.
The arrests follow a five-month operation involving more than 60 staff from multiple agencies - the first of its kind to crack down on invoice scams in New Zealand.
Police arrested six people in Auckland, Port Waikato and Picton after search warrants were executed at more than 25 locations throughout the country.
All are facing charges of participating in an organised criminal group, while five are also facing fraud charges.
The Serious Fraud Office (SFO) alleges the group sold advertising in magazines that did not exist or had "grossly exaggerated" circulation figures.
