One final thing I'll just say is that it's great that there will be more specifications required and the gasfitters association will be charged with the responsibility for assessing these, but we need to make sure they actually have the capacity to do that, because there is a gigantic workforce shortage in New Zealand right now. Are we going to have enough gasfitters to do this work? They have a lot of other things they have to be doing—making sure our houses are safe and fit for purpose, for example. So we need to make sure that at a practical level we can deliver on this legislation if it passes through in its current form.
