An interesting bit of info from one of the members on the Wings over New Zealand aviation forum, as follows:
“I had a really interesting conversation with someone today. Obviously I can't say who but I now have a very clear idea on what the future transport fleet will look like. No surprises really, but Treasury are going to determine what we end up ordering. They have put the brakes on what NZDF wants to do over the next few years (DCP) and essentially we can have 2 A400s or 2 KC-390s or 5 C-130Js... and whatever we get has to be delivered in 2022 (when the current Herc's structure is expected to turn into confetti). A 2 airframe fleet isn't going to work so that leaves just one contender... expect an announcement shortly.”

I believe this member has a pretty good source and this is not just scuttlebutt thrown up on the inter webs by an armchair critic / internet commando.
If true, this is incredibly frustrating.
