Hinemoa walked to Iri iri kapua rock carrying six dried calabash gourds. She lashed them together into a flotation device, waded into the lake at Wairerewai, and began swimming. It was dark. Mokoia Island lay 3.2 kilometers away. Partway across, she reached the fishing stump called Hinewhata, used for catching koura -- freshwater crayfish. She rested, then kept going. Tutanekai did not know she was coming. He had fallen in love with her at hui, watching her from a distance, never having spoken to her directly. He was the son of an illicit affair between Tuwharetoa i te Aupouri and Rangiuru, the wife of Hinemoa's own great-uncle Whakaue-kaipapa. The pair had loved each other without ever exchanging a word. Now she was crossing the lake to change that.

By the time Hinemoa reached Mokoia, she was shaking with cold. She found the hot spring at Waikimihia and lowered herself in to warm up. While she bathed, Tutanekai grew thirsty and sent a servant to fetch water from the lake. Hinemoa saw the servant passing and called out in a deepened voice, asking who the water was for. When the servant answered, she grabbed the gourd and smashed it. The servant returned to Tutanekai empty-handed. A second gourd was sent. Hinemoa smashed that one too. Tutanekai, furious at what he assumed was an insolent stranger, pulled on a flax under-cloak and a tawaru cloak and stormed down to Waikimihia himself. He reached into the darkness under an overhanging rock, seized the stranger by the hair, and demanded identification. Hinemoa answered with her own name. Tutanekai wrapped her in one of his cloaks, led her to his house, and they were married.

The next morning, Tutanekai failed to rise. His father Whakaue-kaipapa sent a servant to investigate. The servant crept to the house and reported an unusual detail: four feet protruded from the bedding instead of two. Sent back to confirm, the servant returned declaring the woman was Hinemoa. Her father Umukaria arrived with a fleet of canoes, and everyone braced for confrontation. Instead, he consented to the match. The couple remained on Mokoia, where Tutanekai built a new pa called Te Whetengu on the island's summit and carved steps down a cliff to a cave where he kept a stone figure of the female atua Horoirangi. What followed was not the simple ending of a love story. Their lives were shaped by the cycles of utu -- reciprocal obligation and revenge -- that governed Maori society. Hinemoa's father was killed by Ngati Pikiao at Lake Rotokakahi during a conflict with Tutanekai. Their younger son Tamakuri was accidentally killed at Tumoana pa on Lake Rotoiti. Each death demanded a response.

After Tutanekai died at Weriweri, Hinemoa composed a lament that is still sung for his descendants. But her later years were marked by harder choices. When her son Whatumairangi was killed at Pikirangi in revenge for an act of adultery, the survivors wanted retribution against Wahiao, Hinemoa's own brother, who had helped orchestrate the killing. They sent Hinemoa herself to meet Wahiao at Te Uenga, on the northeast shore of Rotorua, ostensibly to negotiate peace. While his guard was lowered, the warriors attacked and killed him. The tradition does not flinch from this detail. Hinemoa was not merely a romantic heroine; she was a woman embedded in the complex obligations of her world, capable of both devotion and the terrible pragmatism that loyalty sometimes requires.

The earliest written account of Hinemoa's swim was set down by Wiremu Maihi Te Rangikaheke in 1849. It became one of the most retold stories in Maori tradition and inspired the Te Arawa version of Pokarekare Ana, the most widely known of all Maori love songs. In 1913, French director Gaston Melies shot a silent film of the story. A year later, George Tarr shot another version, claimed to be the first feature film produced in New Zealand. Tekoteko woodcarvings of Hinemoa and Tutanekai, carved by Albert Te Pou, were installed in central Rotorua in 1994. Today, swimmers retrace Hinemoa's crossing in an annual event, competing for two trophies: the larger Hinemoa for the fastest woman, the smaller Tutanekai for the fastest man. The lake has not changed. The distance is still 3.2 kilometers. The water is still cold in the dark.
