Air New Zealand has leased two aircraft to help make up for urgent maintenance on some Rolls-Royce engines on its Dreamliner fleet.
Two of the Boeing 787-9 planes had to turn back shortly after take-off with engine abnormalities last week.
The Transport Accident Investigation Commission and the manufacturers and the airline itself are investigating the planes.
Around 4500 customers had their travel plans disrupted after Rolls-Royce and Air New Zealand made the decision to ground a number of planes.
Air New Zealand has now leased an Airbus 330 and an Airbus 340 from a European charter company.
They are expected to begin operating some Auckland-Sydney and all Auckland-Perth services by next week.
