Straits Air Freight Express (SAFE) was a cargo airline, established in 1950, named for the fact that it encompassed Cook Strait and connected the North Island and South Island (of New Zealand) railway systems from the 1950s to the 1970s.

The main aircraft type that the company operated was the Bristol Type 170 Freighter Mk.31.  The company also operated two much larger Armstrong Whitworth AW.660 Argosy aircraft from 1974 until the end of flying in 1990.
