He’s an actor and comedian from New Zealand. Off the top of my head, he’s been in:

• “Flight of the Concords”
• “Voltron”
• “What We Do In the Shadows” the movie, not sure about the series
• "Our Flag Means Death"

I’m pretty excited by the idea of him showing up in SNW. My guess would be him playing a Mudd/Okana type figure.
