Minister, what I'm concerned about is that this is somewhat voluntary, the system that it's setting up. So the purveyors of certain products can provide a certificate saying that it's safe, but there's no requirement or regime set up by which there's an independent third-party body that's responsible for testing that. The reason I raise this is—I mean, we don't talk about it enough here in Aotearoa New Zealand, but there is no safe level of lead exposure for young children, and there's no way of remediating it once they have been exposed to lead. It has irreversible impacts on brain development. So it's extremely concerning, and I don't think that consumers are aware of just how random it could be that they could be purchasing a product or have a contractor who's purchasing a product off Trade Me that they're using in their kitchen to fill up water glasses to drink from, and it could be leaching unsafe levels of lead. I think it's definitely worth addressing, and so I'm wondering if the Minister can comment on that.
