I can't offer any vet recommendations, but hopefully someone from your area will be along soon
Most vets (round here anyway) have very little pig experience
With regard to vaccinations etc - it's definately worth learning to do this yourself. Either, get the breeder who you're buying your pigs from to show you or get the vet out to do the first ones and get them to explain it to you. The costs for getting the vet to do it would likely be pretty expensive, especially for routine stuff
Kune Kunes are one of the easiest breeds to jag (I think) because they are so tame and friendly.
If erysipelas (sorry, spelling's way off today !) is a problem in your area, if you will have other pigs coming and going or if you are intending breeding it's definately worth doing (if it's castrated boys, purely as 'pets' you'll not need to worry too much
) you need to give 2 jags, 4 weeks apart initially then every 6 months thereafter.
If you have sheep, or if the ground the pigs will be on has had sheep on it recently or there are sheep in neighbouring fields you might want to consider vaccinating against clostridium. It can cause sudden death in pigs, lambivac is the name of the medicine you'll need for that.
The only other thing you need to worry about is worming. They should have been wormed before leaving the breeder (but always double check) and should be fine for 6 months. It's always worth getting a worm count done before dosing them, they might not need treating (especially if it's fresh ground they're on) over-use of wormers can lead to resistance in some cases. Check out Supplies for Smallholders for the worm count kit - only about £10 and worth it IMHO.
Enjoy your Kunes, they are the loveliest little pigs I've ever encountered and I wouldn't be without them
