1. Missing Queen Elizabeth's funeral (26th september 2022): https://en.wikipedia.org/wiki/Queen_Elizabeth_II_Memorial_Day
2. It looks like Anniversary day is following the date for Wellington. Considering that Auckland is the financial centre for NZ, does it make sense to instead use the Auckland date, which falls on the Monday nearest to the 29th of January?
