That is not new, actually. In Germany, they've been using modular construction for many years and their building costs are lower per square metre than ours as a result of that. So we do need to move on and no one really knows why, I think, it's not been adopted as quickly in New Zealand, and it's possibly to do with scale. I know Mike Greer Homes set a factory up in Christchurch not long after the earthquake to construct modular components for homes, and I think we need to really reflect on why that didn't go as quickly and become as successful as quickly as it could have. I note that it's still doing that now in Auckland, I understand. So it's good, and we do need a good regulatory framework, as has been alluded to, to ensure that that works.
