We would use what I would call basic modern investigation techniques. We start with their last place of [Technical difficulty—Editor] with all of the other agencies in the community that will share information with us. We have a single police force in New Zealand. We can have access to other government departments' records if we request them properly—things like our social development agency and a number of other government agencies. We also have what's called a crime line, or a dob-in line, where we receive anonymous information. We also, in the more serious cases, operate human source intelligence—so informants—and all of that information is processed through our intelligence system and refines where we can look to find people.
