The people who work at our border are our national heroes. They deserve nothing but our thanks for the sacrifice that they are making for New Zealand. As I mentioned in question time today, those people working on Air New Zealand flights, who are vital—who are vital—to keeping our country moving, they make sure that our medical supplies get to New Zealand. They make sure that our exports are reaching the rest of the world. They make sure that New Zealanders who need to return home can return home. Some of them are being tested so often they're being tested more than once a day. They're being tested more than once a day because they may be tested before they leave and they may be tested when they arrive at the next place and they may be tested before they leave that place as well. Again, I want to take my hat off and say thank you to them for the sacrifice that they are making to keep all New Zealanders safe.
