Means “Ghost of your ancestors”. Huna, the religion of early Hawaii, taught that each person had two souls.
When one died the earthly soul (unihi-pili) remained earth-bound and descended to the the underworld. The aumakua (higher soul) ascended to the heavens to rejoin the deceased ancestors. This Hawaiian god guides the souls of the deceased on their journey to the afterworld.
