There's a Maori legend about a village which was being terrorozed and devoured by a pair of flying-head monsters (similar to vargouilles or penanggalan) who were magically invulnerable to the men's weapons. Then a canoe appears from the southwest, filled with "strong women". Their leader wields a magic throwing weapon that "cuts with a noise like thunder" and returns to her hand. She knocks the heads out of the sky and straddles them, which negates their masculine magic with the female power of her menstrual blood, enabling them to be killed.
Interestingly, the TV show Xena, while nominally set in ancient Greece, is filmed in New Zealand, and features an Amazon wielding a magic throwing weapon that returns to her hand...
Is there a connection? I don't know - but it wouldn't surprise me. The weapon in the legend is never well described - we only know that it throws and returns, and has a sharp edge. Historically, if you look southwest from New Zealand you're looking towards Australia. Gee, an Aussie with a returning thrown weapon - wonder what it could be?
