Congratulation John!!!!
Welcome to the Country of England.

Well as long as you can satisfy them that you can support your wife
without help from public funds i can assure you that she might get spouse visa, then where you can register her to GP, if she grant a visa when you come over here england, and get all the Priviledge that you get from NHS.exactly the same as yours as long as she is your spouse.

your case is slightly different. cause you get marreid in New Zealand and that is take time to process for your M.C.

All you need to do first for your M.C. need to be registered with NSO from phil. since you get married abroad that will take time unless you get married in embassy in N.Z. where they process M.C. straight away, then if not if you get married on church in N.Z. or attorneys Office and you hold a copy of you M. C. then register it to the embassy of N.Z. so they can forward relevant governing bodies like NSO so thats gona resolve the problem with M.C.

then there is another more might be a problem when you applying the spouse visa since you are retired! how you gona support her here in england unless you got some evidence that you convince them that you can live here in england??? thats e.g. House or other sort of income stocks etc.

I hope that help mate.
