What are some good new zealand online money making websites for teens?

I'm a teen, I'm from new zealand and have a 10hour working day job. I want to keep that job but I need to earn money on top of it when I'm trying to get my goals complete. also trying to handle a hospitality course at the same time. So does anyone know any money making sites that I am able to do for New Zealand? perhaps ones that ain't gonna cost me to sign up or anything, please!!
