Columbia still has the Chinook operating there.
Hevi-lift took a bunch of stuff out of country, but I don't know current status.
Heard a couple of months ago that the Pacific machines were still parked there but there was a fire in the hangar that damaged one machine and destroyed a bunch of parts.
Heli-Harvest NZ has 1 or 2 Mi-17's operating there, last I heard.
All above is first hand high-grade rumour - so take it for what it may be worth!
