They aren't war medals- medals can be given out for different reasons. He did serve in the Navy and the Air Force, though.

I looked it up, they are:

• Queen’s Service Order (New Zealand)
• Coronation Medal
• Silver Jubilee Medal
• Golden Jubilee Medal
• Diamond Jubilee Medal
• Platinum Jubilee Medal
• Naval Long Service Good Conduct (LSGC) (three additional service bars)
• Canadian Forces Decoration (three additional service bars)
• The New Zealand Commemorative Medal
• New Zealand Armed Forces Award
• Garter Star

So none of them are war medals
