I want to reflect for a moment on the health consequences. We know—certainly, the regulatory impact statement told us—that there is an impact on asthma and on glue ear. I think we've probably known that for a while. I think the submission from the Auckland Regional Public Health Service (ARPHS) was really useful through the select committee stage. The select committee stage was very good, actually. We had 120 submissions, and I found them all very, very useful, with experts from a range of domains. But I particularly found the Auckland Regional Public Health Service useful, because they actually quantified the damage. It's enough to say, "Look, it affects asthma, it affects admissions, it affects glue ear." Well, that's kind of an easy statement to say, but give it a number. Give it a number so we can really identify what the impact is and compare it to what other interventions we might be looking at.
