Like new Swazi Kagoule zipper broke?

[Kingston]

The zipper broke on my like new Swazi Kagoule. I only wore it a handful of times. It was purchased from SwaziUSA, which now seems to be defunct. I sent an message to New Zealand, but shipping back and forth seems crazy. Has anyone had luck repairing these waterproof zippers. This is the main (chest) zipper (only a half zip as it's an anorak. The plastic stop thing that holds the two halves together at the bottom broke and the two halves are no longer connected.
