Best smartshare ETFs (in the current climate)

[Jaa]

Can someone please tell me what is the difference between FNZ and NZG? They both track the S&P/NZX 50 Index but the first charges 0.5% and the second 0.2%? Why not just lower the fees of FNZ?

Is this just the old ASB trick of making a savings account less attractive over time and every few years releasing a new, competitive account to attract new money/clients? Tax on those not paying or unable to pay attention in other words. Bad for customers, unfair, unethical and a terrible way to run a business for the long term in my opinion.
