On 24 October 2017 Labour and New Zealand First published a coalition agreement that included migration reduction, provincial growth, and other NZ First priorities as the price of Ardern’s premiership.
Context
Peters chose Labour. Green confidence sat beside. First-term capital-gains-tax abandonment and migration settings owe a debt to this document. Mixed provincial-growth spending is another path.
Swearing-in is 26 October. 2020 majority ended NZ First’s veto. Keep those dates.
A New Zealand prime minister chairs Cabinet and can recommend orders and bills. The House enacts. Police, DHBs, MIQ contractors, and platform companies implement. That office is not authorship of WHO guidance, Australian law, or a later successor’s repeal.

A later repeal, court stay, or successor order would be a different Fact with a different date.
