Trivia: Is Jemaine Clement a judoka?

Apologies if this is too far from core judo discussion. I'll understand if this is deleted.

But I was rewatching Flight of the Conchords, a comedy show about musicians from New Zealand, and at one point, there is a fight when they kick a bongo player out of the band:

Jemaine appears to throw with tani otoshi, then follows up into kesa gatame variant. That doesn't seem like something someone would do instinctively. Has anyone in New Zealand trained with him?
