The Government already has a TPP solution

Radio NZ reports:

Ms Ardern also said the government would try to find a solution on foreign home buyers before she left for the APEC meetings next week.

She said if the government was able to find the right mechanism, it could legislate against purchases of existing properties by non-residents before the TPP trade deal is ratified.

Ms Ardern told Morning Report that would remove one of the government’s main stumbling blocks to signing the TPP, and that would then allow the government to focus on dispute settlement provisions in the trade deal.

The TPP allows countries to impose stamp duty on foreign buyers of property. A 100% stamp duty on foreign purchases would be an effective ban. So Labour already have a mechanism to achieve their policy goal.
