We knew that we needed to do better with contact tracing, because we had the backpacker who developed measles in the Bay of Plenty, who then hopped on Cathay Pacific after doing Air New Zealand, I think it was, to Auckland and then Cathay Pacific back to Germany, infectious all the way. Did we call Cathay Pacific? No. Did we call Air New Zealand? No. Our contact tracing was appalling. We knew that back then, and yet we didn't seem to learn from it. That would have made a substantial difference to this Budget that's being put on the Table here today. We did not learn from it. Did officials even call backpackers around New Zealand, saying, "Look, you're in a high-risk environment for this disease."? No, we did not.
