Police officers are being urged to stay alert for what the Police Association calls the insidious creep of corruption.
In an article in the association's latest newsletter, association president Greg O'Connor says that organised criminal gangs have grown exponentially because of methamphetamine, and that it's naive to think attempts won't be made to compromise officers.
Mr O'Connor says that the corruption of public officials, a craft well-honed by Asian gangs, is now being learned by other groups.
A gang researcher at Canterbury University, Jarrod Gilbert, agrees that officers should be alert to the ease with which they could be bought off.
Mr Gilbert says corruption poses a threat to the police and to society in general.
