Police may charge for the extra work they do at events like the Rugby World Cup under new rules being considered by Government.
A spokesman for Police Minister Judith Collins said she was considering cost recovery options for some non-essential policing.
Police association chief executive Greg O'Connor said that should include the work of officers at Rugby World Cup games.
He said that would bring New Zealand into line with rules in place in Britain.
The English Rugby Football Union would be forced to pay for the extra security they needed at games for the 2015 Rugby World Cup, he said.
