Air New Zealand has revealed 30 of its staff members have been infected with COVID-19.
Radio New Zealand reported on Tuesday about allegations the airline wasn't doing enough to ensure the safety of workers, saying Air NZ wouldn't provide information about how many staff members had been infected with the virus.
On Wednesday, the airline confirmed 30 staff members had tested positive for COVID-19 - 25 of whom have now recovered.
Air New Zealand said in a statement the remaining five of those staff members continue to recover at home.
The airline added, "not all of those cases are linked to employment at Air NZ, and not all are aircrew".
The statement said Air New Zealand was continuing to adhere to the Ministry of Health guidelines.
"Our medical team is actively managing all cases, providing assistance to those impacted and advice to our employees on how to minimise the risk of contracting COVID-19.
"In late March we identified that layovers in Los Angeles presented a slightly heightened risk and as a consequence, all crew returning from this destination have been required to self-isolate for 14 days.
"We are extremely proud of the efforts of our pilots, cabin crew and airport staff who have continued to demonstrate the professionalism and warmth they are famous for during this difficult time for the airline and the country."
The airline has not had a positive COVID-19 case for 12 days, the statement said, with one case confirmed since April 1.
About 27 of its crew were identified as close contacts of the positive cases and have now completed self-isolation without illness.
"Our crew have helped to bring thousands of Kiwis home and are still working hard to keep New Zealand’s vital trade links open and to transport essential workers and freight around the country," the airline said.
