The system has come under increasing criticism recently as people struggle to return to New Zealand through the MIQ lottery or on emergency grounds.
Professor Michael Baker said while MIQ had done its job, it had come with some tough trade-offs.
New Zealand journalist Charlotte Bellis this week revealed she was one of those who had been unable to secure an emergency MIQ space.
Bellis, who previously worked for Al Jazeera in Qatar, is pregnant and unable to stay in Doha, because it is illegal for unmarried women there to be pregnant.
