CHRIS PENK (National—Kaipara ki Mahurangi): Thank you very much, Madam Chair. I've been watching the debate remotely, so to speak, and can I just say it seems to me an excellent discussion in the committee, so I'm grateful to everyone who's contributed. My own contribution will be obviously limited to Part 4, because this is where we are now, and reasonably narrow and won't be unduly lengthy, actually. But I do just want to engage with the Minister, at least briefly, on some of the regulation-making powers within the bill. I acknowledge that the Minister has a legal background, as well as the fact that he holds a particular portfolio in the health space that relates to the substance of the bill.
