His mother Lisa Kairau said her son had been recovering well since being released from hospital on October 20.
When he first got home he had been suffering from bad headaches and memory loss due to a brain injury and it was unsure if he would have any long term effects.
However, his headaches had subsided and his memory loss was slowly getting better.
A concussion specialist had told Ms Kairau that Ayden should make a full recovery.
"He said he feels a lot better, he's healed a lot," she said.
"Physically he is pretty much back to normal ... the memory loss is still there but it is something we are trying to cope with.
"I just have to keep working on reminding him about things and talking to him about different things that he can't remember."
Ayden started back at school today and will take things slowly, she said.
The pair went out of town on a break to help Ayden recuperate for a few days last week and it seemed to have helped, Ms Kairau said.
"We just relaxed, it was good to get away from everything."
He still needs an appointment for his nose and jaw to see if he will need surgery and the concussion specialist will closely monitor his recovery.
Ayden and his mother have been inundated with support and well wishes from people throughout Hawke's Bay, which has been overwhelming, Ms Kairau said.
"We really appreciate everything everyone has done.
"The support from the public has been amazing, it's amazing how many people care."
