Here are a few companies and products that I use myself or that others have recommended to me.
SuperLife are the sister company to SmartShares and both are owned by the NZX. I don't personally use them but a lot of index fund investors sure do!
I changed away from my KiwiSaver provider to Simplicity when they first launched. This is New Zealand's lowest cost KiwiSaver provider and I love using their platform. EASY to understand and I can clearly see my fees which is important to me.
If you buy shares or index funds month after month its really hard to work out IF you are actually making money. I use Sharesights free service to track each of my investments because their math is far better than mine! You could also set up dummy accounts if you wanted to do some hypothetical trading if that was your thing. Love this service.
This is where I go to view my SmartShare investments (although I can also view this through the SmartShare website now).
Gold, pretty gold! This is who I buy (and sell) my gold through. If you want a thrill, then buy some gold and wait for the courier to arrive!
