Whenever anyone puts up the NG bogey there never seems to be any discussion on the effects to the rest of the housing market
You can NEVER change one aspect, it always will result in other "unexpected" changes which quite often nullify the benefit.
It appears to be a socialist thing to pull down the so called millionaire investors, but they forget all the ordinary working people who have saved their money, bought a property for their super fund/retirement income who will be squeezed.
The government has made a total mess of public housing with 3, 4, 5, years waiting lists and it is the private sector who have to carry the load for rental property.
Dropping NG or altering it will be the thin edge of the wedge and people will know that it will be further altered as time goes by so many of them will get rid of their rental properties which will cause a further shortage of rentals available
