Ideally senior civil servants probably shouldn't be making donations to any candidates or political parties. I can't imagine anyone's rights would be trampled if that was a hard and fast rule and it probably should be.
Is it the scandal of the century? Not even close. East Coast was a hotly contested seat with two capable Maori women vying for it, but if Tania Tapsell didn't make it in then that's down to National not giving her a winnable list position and then tanking their own party vote at the same time.
I don't know whether someone thinks this is a good time to put the boot into Kiri Allan after the RNZ speech drama but this is kind of weak.
