"What we hope when we get there is to workshop with other ceramic artists," Ms Waetford said.
"The way we work is we share what we know about our history and culture. What has happened in the past is that people have ended up collaborating with each other." "I enjoy seeing the other cultures and people and places," Mr Hikuroa added.
There are about 100 artists travelling to Guam from New Zealand.
The trip is particularly special for Nga Kaihanga Uku. The late Colleen Urlich, an influential Maori clay artist from Dargaville, applied to Creative New Zealand to fund the trip.
Mrs Urlich was supposed to attend the festival with the group but she died in September - only a week after the Maori arts world lost fellow Northland clay artist Manos Nathan.
"It's hard. It's hard to talk about it but it's okay. It's very weighty because their responsibilities have been passed on to us," said Mr Hikuroa.
"Colleen and Manos will always be with us, they'll still be there in some way," said Ms Waetford.
Mr Hikuroa said Maori clay art was a relatively new art form in New Zealand.
"Well next year it's our (Nga Kaihanga Uku) 30th birthday.
"If you look at the beginning of carving and weaving, we're probably the youngest tradition."
