International law enforcement agencies say crime and corruption is on the rise in the Asia-Pacific region.
New Zealand Police and Customs, the United States Department of Homeland Security and representatives from 21 other countries and the United Nations, have been meeting in Christchurch.
The agencies say illegal drugs, child pornography, fake medicines and illegal logging are threatening New Zealand and the wider region more than ever before.
Illegal drugs make up an estimated 80% of trans-national crime, with the market in New Zealand estimated to be worth $200 million per year.
The UN Office on Drugs and Crime says trans-national crime is galloping away and co-operation is key to dealing with international criminals.
