Dagger for Identification

[Jerseyman]

This is a recent purchase which I have not yet received. These are dealer's pictures, and of course I have no dimensions to share. Obviously it will need cleaning when it arrives. It also appears that the blade is wedged in the hilt using paper.

I am unsure of where this dagger comes from as I've not seen this shape before, and I would welcome any information. I would assume one of the Pacific archipelagos, but which one?

Thanks
