Funds are where lots of investors put their money together, and then have the money invested into different shares, bonds, or bank deposits. There are many types of funds, for example, active funds (where there is a professional fund manager who decides where and how to invest the money), and passive funds (where the money in the fund is invested in a market index e.g. Top 50 NZ shares). Funds are one of the most accessible investments, as you can start with as little as $50.
How to invest: You can buy funds through a platform like InvestNow or Sharesies.
