The popular Brockville School principal was left fighting for his life after being knocked off his bicycle by a four-wheel-drive vehicle in Main Rd, Fairfield, on Valentine's Day.
His wife, Stacey Hickford (38), said their children, Grace (7) and Toby (4), were "coping as best they can'' and her husband was making progress with his rehabilitation.
"It's very small progress but it seems to be consistent.
"It's very small steps, but if you look back from what he couldn't do three weeks ago, you would say it was big progress.
"It's difficult seeing him battle with things you can do, [the sorts of things] that you take for granted daily,'' she said.
Mr Hickford (43) was moved from Dunedin Hospital to Wakari Hospital's Isis unit about a month ago, was now walking with assistance, and was in a "post-traumatic amnesia stage'', she said.
He had a bleed on the right side of his brain as a result of the incident but had always recognised his family, despite his injuries.
"The brain is just not processing things correctly,'' Mrs Hickford said.
"We don't know how far back he has a blank. He remembers nothing of [the accident]. Anything he knows about it, he's been told.
"He kept forgetting why he was there [in hospital] ... [but] he's aware that he's principal at Brockville School.
"He gets very emotional. He's devastated really. A bit of anger comes out as well.''
A poster was now displayed on the wall beside his bed to remind him of what had happened to him after the keen multisport athlete set out on a 40km bike ride from his home.
A police officer knocked at the door and told Mrs Hickford her husband had been seriously injured.
"My whole world fell apart then.
"It's been devastating, frustrating, horrifying, all the emotions you can basically imagine ... a roller-coaster,'' she said.
Grace and Toby did not know the extent of their father's injuries at the time but Mrs Hickford had given them more information as time went on.
They visit him almost every day.
The couple had some animosity towards the driver, who had not made contact since the accident.
"He hasn't inquired into how Craig is since the accident.
"My whole world has been turned upside down ... and he gets to just continue his life as normal,'' she said.
The family were grateful for the support they had received since the incident, especially from the Brockville community, Basketball Otago, where Mr Hickford was a board member, and family friends.
"Just a tremendous thank-you to everybody,'' Mrs Hickford said.
"It's hard to put into words how much it means.''
It was not clear whether Mr Hickford would make a full recovery but the family was hopeful.
Brockville School board of trustees chairwoman Rosalie Feleti-Ivala said there was "a huge amount of support in Brockville for Craig''.
"When Craig joined our school he and his whanau became a part of our community. So when he had his accident it was natural for us to offer and continue to offer support to Craig's whanau,'' she said.
Acting principal Tania McDonald had done a "fantastic job'' in Mr Hickford's absence, she said.
Senior Sergeant Brian Benn, of Dunedin, said a man had been charged with careless driving causing injury in relation to the incident and would appear in the Dunedin District Court on Tuesday.
