This is irresponsible and wrong. MPs are essential workers, but Collins travelling to Wellington is completely unnecessary for Parliament to fulfil its function. National has Wellington-based MPs who can speak for the party and cast its proxies. But then they might get the media attention instead of her (or worse, outshine her).
Travelling from a covid-hotspot to a less-infected zone, with the consequent risk of spreading the disease throughout the country, solely so you can get media attention, is the action of a sociopathic narcissist. And if Wellington gets covid cases as a result, we will all know who to blame.
