The family home is ring fenced.The labour party wants to reverse the damage national has created where more people are paying rents they can't afford then ever because house building hasn't been able to keep up with demand.And house prices have soared beyond first home buyers etc.
Immigration numbers have a part to play in this and overseas buyers make up somewhere in the 3 to 13% of the buyers(maybe not atpit). The figs aren't available for us to decipher(ask national) but labour think its at the higher end.
The working group (outside experts i believe) for Labour will come up with the best solution for a capital gains tax to plug the gaps the speculators are taking advantage of it and paying no tax in some cases by running rentals at a loss. It will take over year. If its good Labour will want to put it in place and let the voters decide at the next election how good it is.
Its a complicated fix with fishhooks and needs to b done right first time hopefully.
