"Monday to Friday, they get poked and prodded. As a family we want this weekend to be a really quiet weekend to rest then on Monday all the right people can make the right decisions for him," Kade's grandfather said.
"He's still got surgery to go ahead, which is hopefully in 10 days' time and that's quite a delicate operation as I understand it.
"He's stable. We're very fortunate that he's talking and he hasn't lost any of his memory. He's able to communicate what he's feeling and if he's in pain. "He's still a sick wee boy. We've got an unknown and very tough road in front of us."
Kade's injuries were also causing difficulty when medical staff had to move him.
"It's frustrating for him as well. It's all got to be managed and handled very quickly."
Family members remain at Kade's side at all times and were now waiting to see when he would be moved to Auckland's Starship Children's Hospital.
Kade's grandfather said there had been overwhelming support from the community, including the school PTA, which had set up a Givealittle page.
So far 186 people have pledged $6200.
"We're blown away. It's jumped quite quick and I think that's because people realised that Kade is a sick boy and he's got a long way to go."
A 9-year-old boy involved in the incident has been spoken to by police.
