"There were some fantastic entries but part of the decision on the winners was based on how achievable the designs were to make in glass," Ms Rees said.
"The artists said making something new and different was quite a challenge and they were also working with people they hadn't worked with before. They worked really well as a team.
"It was so cool to see a kid's drawing made into a 3D object. Kahu wasn't able to be here on the day but her mum told us she was very excited. It was really great having so many people here watching the whole process."
The competition winners will get to take their glass creations home once they have been finished off this week.
