Police cost recovery took place in Britain and Australia, he said.
In the briefing to Mrs Tolley, released yesterday, the police sought the opportunity to "recover the costs of providing some services 'over and above' [their] main functions" as one of their bids for new legislation in 2012.
The detail of the proposed law, however, has been withheld.
Mrs Tolley said she was working on the proposal, but there were logistical difficulties to sort out, such as how police would charge a private company and what the criteria would be.
"My understanding is that it's for where they're doing something for a for-profit event, where someone is making some money, and the police are there, paid for by the taxpayer.
"It certainly won't be on the agenda for legislation for 2012 ... there's a lot of legislation on the Order Paper now." She supported police finding new ways to generate revenue because "there isn't any more money coming from central Government for the next four years".
Police Commissioner Peter Marshall told the Herald in December that he had not yet ruled out looking at cost-recovery for policing public events.
"In a lot of those, it's in the interests of police to be present. We have a public event at the bottom of Queen St for the Rugby World Cup, for example, and where do you draw the line between our obligation to keep the peace versus charging some corporation for a commercial event?
"The line's a little bit blurred, and we have an interest in being present at certain events, whether of a sporting or a concert-type nature, because we know criminal activity may occur."
