Welcome Bucks fizz
Sorry i dont think i can really answer you question.
However, My hubby was looking into football in Christchurch and it turned out to be more popular than he thought it would. There are lots of amateur clubs, who play for fun. Some of these were adult teams but i am sure they have lots of kids teams also.
Check this one out... hubby was lookin at this... plus they have kids stuff!
