Let me just draw an analogy, because one of the most obvious solutions—apparently we should just ban the virus. If we're mean to the virus, it won't come into New Zealand! That seems to be the implication from at least one member on the other side. If you raise your eyebrows in a sufficient kind of a way towards the virus, it won't dare cross the border. But let's just be really clear about that: for the last several decades, including the nine years of the last National Government, we had a zero tolerance to biosecurity incursions in New Zealand. How did that work out for us? There were 199 biosecurity incursions under the last Government despite their stated zero-tolerance approach for that—including Mycoplasma bovis, which has cost the country millions. That happened under their watch. If there was a way to make our border 100 percent foolproof when it comes to viruses and other things that might want to try and get into the country, every Government would have done it by now. The thing is there is no such thing as a risk-free strategy here.
