Things to Keep in Mind When Choosing an Investment Platform

The rise of digital investment platforms has made it easier than ever to buy and sell shares, ETFs, funds and other assets. However, it’s still important to know which platform will work best for you - and you’ll only be able to decide if you shop around a little.

If you’re looking for the best investment platform in New Zealand consider the following while you choose:

• Eligibility - Not all platforms are right for all investors - Kernel Wealth is only for NZ citizens and PRs for example, and can’t be used if you live abroad
• Fees - Management fees can eat into your investment’s performance gains, while transaction costs can kick in every time you buy or sell. Compare all possible costs before you sign up
• Cross currency costs - If you plan to diversify your portfolio into other countries you’ll need to understand how your platform manages currency conversion, and any fees that apply
• App performance and services - Check you find the platform app easy and intuitive to use before you start - and look out for providers which have a reputation for good customer service and ways to talk to support 24/7 if you can
