He also attended Henry Hill School in Napier and Napier Intermediate prior to high school.
One of Miller’s friends posted on Facebook that he would be sorely missed.
“You were so cool, always had me in fits of laughter and cheeky giggles whenever we talked.
“You will be missed my friend, you really left a mark and definitely made an impact in the lives of not just mine but so many people.”
Another person added he died trying to help others.
“[Your] willingness to help others without wanting anything in return was one of the many things I admired about you, you were courageous and committed to ur beliefs.
“You are and always will be an inspiration to me my brother.”
Police said in a statement they extend sympathies to Miller’s family and friends. His death has been referred to the Coroner.
