The Ministry of Business, Innovation and Employment (MBIE) said only a third of the amount billed for quarantine up to February 28 - $10.7m out of $30.2m - has been paid so far. The Ministry said invoices ask for payment within 90 days. After 91 days they become overdue, and are a debt due to the Crown. “MIQ sends a reminder 30 days before the due date to returnees, which includes details of how to pay, how to apply for an instalment plan, and what to do if the person considers they are not liable or are exempt. “After the due date a further letter will be sent requesting payment. This letter also contains details about how to apply for an instalment plan.”
