Hon DAVID PARKER: That would depend upon future interest rates—in respect of which, I note that upon the announcement of our policy, the New Zealand exchange rate immediately dropped because there was a baked-in expectation from the market that interest rates were going to have to be raised by the Reserve Bank to head off a housing bubble. As a consequence of what we've done, interest rates will be lower for longer than they would otherwise have been. I also note that Westpac reported, following their analysis, that removal of deductibility of interest would remove the 10 percent extra growth they expected in house prices over the rest of the year. So, in our view, on this side of the House, we're actually doing something that's working.
