Demand to be part of the home isolation trial is expected to be high.  

It will allow 150 people to travel overseas and self-isolate for a fortnight when returning.  

Business travellers will be able to submit expressions of interest from 9am today - but they need to be within 50 kilometres of Auckland or Christchurch airports.  

Enztec CEO Iain McMillan told Kate Hawkesby they're hopeful the trial will become a full rollout early next year.  

"The demand is no different to the demand for MIQ spots, where there is 10s of thousands of people."
