The group then made their way into town and from there Ohinemutu. After the eruption the survivors made their way to Ohinemutu where the people of Ngati Whakaue fed and housed them, Whaea Fairhall said.
She said the school was reenacting the steps of the survivors, and had also made 118 food baskets.
"We will be eating potatoes, kumara and soup - the food provided to the survivors at the time."
The whole school took part and had previously studied the event in class.
"I do think it's very important that Rotorua, as a whole, should know about it, because it's a part of our history, but especially important to the tribes of Tuhourangi, Ngati Hinemihi and Ngati Rangitihi."
Student Maia Maurea Pirini-Werahiko, 14, said one of her favourite parts of the day had been the walk, "because we are doing what our ancestors did".
It was also fun dressing up in the clothes of those days, she said.
