Air Freight NZ (TFR, Auckland International) will replace its fleet of five CV-580(F)s with B737-400(F)s between February and May 2016 parent firm Freightways has disclosed.

In a statement, the New Zealand logistics firm said the trio of jets would be dry-leased from Airwork Flight Operations (AWK, Auckland International) whose parent, Airwork Holdings Limited (AWK), will form a joint-venture company with Air Freight NZ's parent, Fieldair Holdings Limited (FAH).

"Customers of the JV company will be Freightways' express package businesses and NZ Post’s Express Couriers (ECL) business. If demand warrants it, capacity will be made available to other freight operators," the firm said.

The fleet of five Convairs will be put up for sale once the B737s arrive.
