"[He] was involved in a lot of school activities. Students are being encouraged to support each other and to look out for the welfare of their friends and colleagues."
Zach's friend Samara Smith-Riggir yesterday said he may have been wearing headphones when he stepped in front of the train, which heading to Kinleith from Hamilton.
"In class he usually had one earphone in so he could listen to music and to the teacher at the same time," said the 14-year-old.
Matamata Police Sergeant Graham McGurk said a post-mortem examination was being carried out today.
"The investigation into how this tragedy happened is continuing, as is an investigation by the train's operators and the boy's death has been reported to the coroner," Mr McGurk said.
