Mr Aken, who runs a data storage company, said as a father of three boys, he knew how important technology was for young people.
"As soon as one of these laptops breaks down, they lose everything."
He also gave Joshua five gigabytes of free back-up storage, so he wouldn't lose his files if something happened to the new laptop.
Joshua and Ms McCutcheon picked up the new Acer laptop yesterday.
Ms McCutcheon said the generosity had given Joshua and the family a massive boost. "It's just blowing me away ... He [Mr Aken] doesn't even know us.
"It's nice there are some people out there that care.
"It makes me feel wonderful. It just shows there's still some humanity left and some compassion."
Joshua also received a bag of presents which had been dropped anonymously to Hawke's Bay Today's office.
The McCutcheon family has set up a Givealittle page to raise money for their $1000 insurance excess after the burglary cost them $6000 worth of belongings.
The page had raised $420 last night.
