No Kiwi based coaches have right quals. So can rule them all out.
Though I do remember one possible avenue raised last post season, was Schmid (who has a Pro Licence?) being appointed as a sort of HOF, and Buckingham/Greenacre effectively under him as the hands on Nix coaches.
To have Schmid do any actual coaching would of course be stupid. For NZF to actually help the Nix even more ridiculous.
Bucky does.
Also Ricki Herbert. How weirdly sweet if Ricki completed the cycle for the nix and then went to the next NZ incarnation (ala Kinghts).
