Hon CHRIS HIPKINS: Yes, absolutely. I've always said, and I think the Government has always said, that our person-to-person contact tracing system is the mainstay of the system, and I'd point out that no Government anywhere around the world has found that one magical technological solution that would short-circuit that process. What we've always said is that the COVID Tracer app helps to speed up the manual contact tracing process, but that will always be the mainstay of the system.
