I'm 16 and have been working part-time now for a while I have managed to save up around $14,000 which is all sitting in a normal savings account collecting a small bit of interest (some is automatically going into a kiwisaver) I'm just wondering if their is anything I should be putting this money into or doing with it to help me in the future. If it helps I generally make around $250 to $350 a week.

Any help/advice would be more than appreciated.

Thanks in advance

edit: I've heard an index fund would be good long term but unsure of how to go about this. Also what % of my paycheck should be going into my kiwisaver?
