Tanya Smiley who attended the school in its earlier years said through her interpreter Lisa Smith that being in the mainstream class was difficult to deal with.
"When I was at school we were told to try and speak and be more vocal, we weren't allowed to try and sign anything which made it very hard and frustrating," Smiley said.
"When I moved to the deaf unit it made it easier, but we still needed to learn sign and try and communicate with others."
At its peak more than 30 children attended the deaf unit, but over time the number of enrolments dwindled as parents wanted their children in mainstream schools.
Nowadays Smiley sees that the schooling for children is much better and since 1996 there has been a Hawkes Bay Deaf Club, which she has been president for the last two years.
"The schooling for deaf children has gotten better now with technology and having the Deaf Club is a great way for us to socialise and come together as a community," Smiley said.
But for Smiley she can't wait for the weekend.
"I'm excited for the weekend, some of my class mates I haven't seen for over 40 years and they are coming from all over New Zealand and Australia for this reunion."
