Fortunately Max is only required to have yearly check-ups to monitor his progress, but the news the family received five years ago turned their world upside down.
Mum Monique would travel every six weeks from their Hawke's Bay home to Auckland's Starship hospital with her son – one of four children.
But the Child Cancer Foundation introduced Max's father John and three sisters Giana, Leila and Amalia to the Beads of Courage Sibling Programme, who provide recognition and emotional support to siblings impacted by the serious illness.
Monique said the family were connected with a family support coordinator, Shannyn, soon after Max's diagnosis.
"Amalia was only four when Max was diagnosed, so she was just starting school when we were in the thick of the treatment plan," she said.
"Shannyn set me up with the Beads of Courage Sibling Programme to support all the girls through their experience, but especially for Amalia."
Monique said the programme gave the girls something that was all about them, instead of being all about Max.
Every time Max and Monique had to leave for treatment, when the girls received special awards at school and on special occasions such as birthdays and Christmas, Monique would sit down with her daughters and give them a packet of sibling beads.
Monique said Amalia's beads were especially effective as a tool to help with the anxiety she was experiencing because they helped her feel included.
"Younger kids see the beads as a treat that only cancer patients get, so for Amalia to get her own was very special. I saw so much growth in her throughout our journey."
During the course of her son's treatment, the mother of four said the Child Cancer Foundation was amazing.
As well as providing day-to-day emotional and practical support, the family support coordinator was particularly focused on ensuring that Max's sisters were supported through their experience.
