"She was an absolute allrounder. She gained distinction for piano, she was netballer of the year and did athletics and triathlon. She obviously had a huge future ahead of her with sport.
"But everyone remembers her for her smile. She had a fantastic smile."
A large oak tree in the central playground at Sumner School is serving as a memorial site.
The main tree trunk is so full of cards, origami cranes, flowers, and balloons that people have resorted to hanging cards on branches with ribbons.
Jewellery hangs from the tree amid love hearts and colourful tributes.
Paul Wilkinson, acting principal at Sumner School, where Ella and Abi were former students, said a memorial by a tree had been set up for friends and loved ones to leave flowers and messages.
"There have been lots of people constantly visiting the tree," he said.
Mr Wilkinson said the tree was chosen because it was close to where the school's Year 7 and Year 8 pupils were based.
"The Sumner community, the children and staff have supported each other beautifully in this very sad time, and will continue to do so."
He said the Ministry of Education trauma team had left the school for now, but were available if needed again.
Hone family spokesman Darren Wright said the families' focus was slowly turning to funeral arrangements.
"We're working through that process now."
