The Ministry of Health is no longer providing schools and workplaces with free COVID-19 tests. In Wellington, you can order free COVID-19 tests through several channels:

1. Book My Vaccine website: You can book a free COVID-19 test through the Book My Vaccine website. They provide information on testing locations and booking options.

2. Healthline: You can call Healthline at 0800 358 5453 if you have symptoms of COVID-19 or if you have been in contact with someone who has tested positive. They can provide guidance on testing and may be able to help you book a test.

3. Testing Centers: There are various testing centers and pharmacies throughout Wellington where you can walk in for a free COVID-19 test. See more at https://www.healthpoint.co.nz/covid-19/wellington

Please check the latest information on testing options and locations on official government websites or local health authority pages, as procedures and availability may change over time.
