Were can a 15 year olds in christchurch get a job?

Hi from Australia. I visited Christchurch in New Zealand a few years ago, and remember it as a small city. I would try the local supermarket to see if there are shelves to stack or collect shopping trolleys/ carts. [Called Trundler in New Zealand.] Also you could do a paper round, ask a newsagent. Perhaps work in the small farms nearby. If you like gardening and cutting lawn or doing chores for old people. Best of luck with your endeavours.
