## Context

MMP arithmetic, not a presidential decree, made the government. NZ First extracted policy concessions. Later KiwiBuild and COVID files are other dates. Office is not authorship of every 2018 bill.

The 2020 election majority is a different date. Resignation 2023 is a different date. Do not convert a swearing-in into a housing coefficient.

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.

## Evidence and sources
