It has also chartered an additional eight freighter flights per day to improve Express Post priority service deliveries across major capital cities in a move to soothe frustrations over delivery delays.
Acting chief operating officer Rod Barnes warned the service was still experiencing significant delays due to limited flights, hygiene and social distancing requirements to mitigate the spread of the coronavirus.
"The majority of parcels are still arriving on time, but we ask and thank our customers for their patience, as we work as hard as we can to get parcels to you as quickly as possible," Mr Barnes said.
