The Patupaiarehe people lived around the lakes of Rotorua at a place called Ngongotaha hundreds years ago. These people were fair skinned and they were very good gardeners.
The Tipua people were giants and they were very bad tempered. These people wanted to take the beautiful lake and the land away from the Patupaiarehe people.
One day the Tipua war party marched through the Mamaku forest towards Ngongotaha. The Patupaiarehe people became very scared. They asked their leader to save them with his magic spell.
Tongakohu lit a fire and began chanting his magic spell. Soon the Tipau giants started feeling tried and they decided to stop marching and take a rest. After a while the Tipau giants wanted to move but they could not because they had turned into rocks. Finally, Tongakohu was able to save his people from the Tipau giants.
