Hine and the Tohunga Portal is a fast-paced fantasy adventure. Hine and her brother, Hōhepa, unwittingly step through a portal into an ancient realm inhabited by the atua Māori (Māori deities), Kea bird tribes, patupaiarehe (fairy people), moa and giant eagles. This world is in turmoil as evil sorcerer Kae has built a cursed army and intends to rule this world and everything in it. He sees the opportunity to dominate the modern world as well, by kidnapping Hōhepa and using his life force to reopen the portal between the worlds. This sets Hine on a quest to learn ancient knowledge from the goddesses Hineteiwaiwa and Mahuika and her ancestors, find the medicine to revoke the curse on the warriors and gain the support of the Kea and patupaiarehe to fight Kae and rescue Hōhepa.
