New Zealand To US Via Dx Mail And Singapore

Received a postcard from New Zealand bearing this stamp via DX Mail (interesting that the cancel doesn't even show a date). Is this a competitor to the national post office?



What makes this more interesting to me is that the reverse side of the postcard contained this label from Singapore Post:



Maybe it went from New Zealand to Singapore to USA?

That's all very strange.

DX Mail
(I am assuming they have a NZ branch)
I don't recall seeing DX Mail before.

The Singapore label is a PP = Postage Paid
the number refers to the bulk mailer
(It may be singapore airlines)

I know "Kris Flyer" is PP 1621
