The Bell Iroquois has been in RNZAF service since 1966. As early as the 1980s the RNZAF considered upgrade options for the Iroquois, but these were not pursued.

The Iroquois’ performance limitations during operations in East Timor between 1999 and 2002 reinforced the need for urgent action.
The Eurocopter NZ NH90s from Marignane, France has been selected as its replacement

RNZAF maintenance staff and aircrew have completed training at the manufacturer’s facilities in France, and commenced Operational Testing and Evaluation (OT&E) will begin. This lengthy process is required to ensure that the equipment that has been purchased is ready to undertake the roles, tasks and missions that Government require. The completion of OT&E will see the NH90 MUH take its place in the NZDF which has been so proudly reserved for the Iroquois for over 40 years.
