Eleven of the Eagle Air planes grounded last week will be back in service today, but some disruption to flights may continue.
Air New Zealand grounded all 18 of the airline's Beech 1900D aircraft on Tuesday after cracks were found in the tails of three planes.
Other Air New Zealand planes have been drafted in to help cover some flights, but there could still be changes to flight times.
Passengers can check flight times on the Air New Zealand website airnewzealand.co.nz.
