What's it like in Auckland, where the problems have been most pressing? House builds have gone up, from 10,800-odd in 2017, by 60 percent to over 16,000. Where's the growth happening? Well, this is what I find really interesting. Apartments have gone down—that's because we've banned foreign buyers, because they were being predominantly purchased by foreign buyers. That building effort is now going into semi-detached townhouses, flats, units, and other dwellings. The number of single houses is roughly flat, but the number of town houses, flats, units, and other dwellings has gone up from 2,200 to 7,200 a year—a 300 percent increase in the typologies of smaller houses that people can afford to buy.
