"It's been such a productive and exciting week."
She said the musicians who ranged from 5 years old to 16, had been amazing.
"It's been great to see them really enjoying music."
Daily activities have included master classes, group lessons, yoga, theatre sports, orchestra, piano accompaniment and extended repertoire classes.
"It hasn't all been music," Ms Allen said.
The week saw three international and seven local tutors imparting their wisdom.
Haruo Goto, Zohara Rotem and Julia Breen have came from Australia while Lois McCallum, Emma Fetherston, Elizabeth Lau, Anna-Marie Alloway and Gregory Squire were from around New Zealand. Also tutoring were Hawke's Bay's own Ken Keyes and Jan Beck.
Another part of the workshop has been the "teenage teacher training".
"We could always do with more Suzuki teachers, so it's great to see them immerse themselves even further."
Ms Allen said today's concert will involve everyone from the workshop in one form or another.
The New Zealand Suzuki Institute (NZSI) was formed about 20 years ago. Today there are approximately 300,000 teachers and students in 34 countries worldwide.
