The police, fire service, St John and Rotary were all volunteers.
The expo involved interactive activities.
Mr Nikora said there was a rock wall which focused on restraints when driving, putting it into perspective that you would not climb a wall without restraints so why drive without a seatbelt.
There was also a snakes and ladders game which focused on understanding alcohol impairment and the road rules, testing people's knowledge, and a simulator showing how difficult it was to drive and text.
Te Utuhina Manaakitanga were at the expo with activities around impairment and offering help for anyone dealing with alcohol or drug issues.
One of these activities was putting a cup on a wheelie chair and having to navigate it through cones with goggles on which offset vision.
This was to show how dangerous it can be to drink and drive and just how it impaired your skills.
"It's really great the support we get. The schools push it and come along."
He said hopefully the expo got students thinking about their driving behaviour and would put them on the path to being safe drivers.
Western Heights High School student Kiri Tuhakaraina, 16, said the expo was fun and she liked they were trying to get the message across drink-driving was a stupid idea.
Regan Curtis, 15, also from Western Heights High School, said she liked the reality of the videos being shown.
She thought it was important to be taught about the consequences of actions.
Pariss McKelvey, 15, said she had learned about not drinking and driving, and thought such expos were important so you did not have to face the consequences later on in life.
