Education Minister Chris Hipkins says the Government is looking to enable international students to return to New Zealand if they can be quarantined safely.His comments follow an assurance from Victoria University Vice-Chancellor Grant Guilford, who told the Epidemic Response Committee on Tuesday that international students could be quarantined at zero risk to public health.The international education sector is worth $5 billion a year, and the education sector, including secondary schools, has been feeling the financial squeeze from the borders being closed to non-New Zealanders.
