Any ideas on this paddle/club?

I picked up this nifty little paddle at an estate sale this morning... It's solid, hard and kinda light-weight. It's about 14" long and 4" wide at it's widest.
Lotsa great detail on one side and smooth on the other:

Any ideas on origin??? Mahalo!

I think thats a Maori Patu (or a mere, meremere, kotiate) probably made in New Zealand from matai wood, the carving is quite detailed so I suspect it was made in the 1960's. The club is missing its strap which would go through the bottom hole.

Quite a nice tourist piece, and a jolly good find.
