Consumer have provided the following info to let you "opt out" of the price increase. I haven't tried it, so not sure if it will work for everyone, but might be worth trying. https://www.consumer.org.nz/articles/you-don-t-have-to-pay-the-microsoft-365-price-increase
Yep I did that and it worked, it changed it back to $12 a month for me.
