Ultimately she was just okay, she could have been transformative. Her first term was hampered by being in coalition with a dinosaur, but when she won the next election with an overwhelming majority (in an MMP format) I had high hopes.
To be fair to her, she has dealt with a lot; having a baby, a deadly volcanic eruption, a deadly terrorist attack and a global pandemic. Her decision is understandable, the amount of abuse she's been getting from the ever increasing number RW nut jobs over here relentless.
I imagine a successful career at the UN awaits, and for managing the pandemic arguably better than anyone else, she leaves with my thanks and respect.
My fear now is a Right Wing coalition victory at this years election and we see the same type of politics/politicians you are being served up with in the UK.
