Hon GERRY BROWNLEE (National): Can I thank the Minister for beginning a discussion on the issue of who may exercise the powers under this bill. It is the one area that the National Party has some concern about. It won't stop us supporting the bill through the balance of its House stages but I think, given that courts these days will often derive some of their determinations around the law from what is said in Parliament, then I think there needs to be a greater articulation by the Minister of exactly what the limits are on the powers of non-sworn officers of the Crown—in other words, on Customs officers, on the Department of Conservation (DOC) rangers, and any others who might be included in that body of enforcement officers that the broad term "enforcement officer" is used for here in the bill.
