What is "wahinepio"

Kahakuhaakoi Wahinepio (died 1826) was a Hawaiian chiefess and member of the royal family during the Kingdom of Hawaii. Wahinepio means captive women in Hawaiian. Sometimes she is called Wahineopio, or an extra ʻokina is added, calling her Kahakuhaakoi. She was also called Kamoonohu. She was considered Kamehameha I's third favorite wife and served as female Governor of Maui, an act unheard of at the time in the western world, but common in Hawaiian history.
