When economist Gareth Morgan launched his bid for Parliament last year, he compared himself to Donald Trump because of his anti-establishment approach.
The two men now have another thing in common - a tendency to be short and sharp on Twitter.
Morgan, the leader of The Opportunities Party, was involved in an extraordinary argument on the social media site Sunday night in which he called critics "whores" and raged against "bottom feeding" tourists and "PC culture" in New Zealand.
The argument started when Morgan criticised Tourism Minister Paula Bennett's decision to rule out a tax on tourists because it would make New Zealand too expensive to visit.
Morgan tweeted that a tourist tax was not about imposing costs, but about "crap people, crapping on us with contempt, bottom feeders and bleeders". He suggested a ban on camping in public places unless in a self-contained camper.
