Oct 28 (Reuters) - Air New Zealand Ltd said on Thursday it had suspended its cash burn guidance due to uncertainty about domestic COVID-19 alert levels and had drawn down another NZ$105 million ($75.22 million) from a government debt facility. The airline said it was operating around 40% of its domestic network given tough travel restrictions in the country’s largest city, Auckland. Air New Zealand last month said it was burning through around NZ$25 million to NZ$35 million of cash a month in the domestic market. The closure of a quarantine-free travel bubble with Australia had led to another NZ$20 million to NZ$25 million a month in cash burn, it said at the time.
