The Minister said in answer to my question, quite simply, that officials didn't know whether this would make any difference to rents and didn't know whether it would make any difference to rising house prices. Well, I would suggest that they simply have a look at this history of the last three years and see what's happened, as I said earlier: a $250,000 average capital gain on an average house price in New Zealand in three years, and a brightline test that will only take $70,000 from them. I'm not making a case for more tax, by the way. All I'm saying is that you cannot use the tax system to solve a problem of supply, and the thing that is really very, very irritating, listening to speeches today from the Prime Minister, from Mr Robertson, and from others who have made comment in the media, is the complete denial of the supply problem. The idea that you can put up three hundred and something million for pipes and roads and goodness knows what else, and then that's going to solve it all, is utter rubbish, because unless there is consented land, then there is no further supply, and where there is consented land, there is no shortage of capital for its development.
