More than 600 businesses applied for just 150 places in the trail.
One of the successful applicants was Mark Ulrich, director of UMC, a Christchurch-based engineering company that sells wire fabrication machinery around the world to the fencing industry.
He spoke to Lisa Owen:
The businesses had to meet strict criteria, which included having somewhere to stay alone.
The property that they isolate in cannot share a ventilation system, so no apartments are allowed.
It also has to be within a 50km radius of Christchurch or Auckland airports. And the traveller needs to return to those cities on a direct international flight by December 8.
The successful applicants were told last week.
