This is likely to reduce the attraction of quick flick transactions. It will also level the field a bit when compared to building new houses, but not much.
In my experience, renovating in Australia I was far more likely to buy, reno and hold than buy reno and flick because of CGT. Some may disagree. Just an opinion.
I see a lot more talk of buying 10 investment long term rental type strategies in OZ than that sort of talk in NZ.
The flip side in OZ, when it comes time to retire, you can move into the house I believe to avoid that situation. One I am now far from privileged enough to do.
The GFC did dip the RE market here, 8% ish? But nothing near what it should of thanks to the government pulling smoke and mirrors to prop our economy up which is what has imo started the initial snow ball of the current bubble.
