Rt Hon JACINDA ARDERN (Prime Minister): I'd like to answer this question in two parts. Firstly, as a Government, we have worked hard to scale up our contact tracing significantly. This has included providing $55 million to support public health units and contact tracing; extended capacity to make 10,000 calls per day; and ensuring public health units are using a national contact tracing system, with the final one now coming on board. However, the suggestion that this should be done as a tool to reopen our borders is wrong. Contact tracing is a tool to keep people safe; border controls are too. At a time when cases are surging globally and the World Health Organization says, "the hard reality is this is not even close to being over", to suggest that we should simply reopen the borders and rely on contact tracing, no matter how good it is, is, frankly, dangerous.
