In April the 4-year-old was diagnosed with soft-tissue cancer that had spread to his lungs and various bone sites.
He has since fought off cancer from his bone marrow and his mother, Fritha Beaton, told the Otago Daily Times on Thursday things were looking up for the Arrowtown family.
"He seems to be doing well, and he's looking better.
"Everything seems to have plateaued, as we haven't seen the consultant in a while, which is a good thing."
Angus' progress had been so good the family of Gordon, Fritha, Kate (6) and Angus were all able to return home for six days last week.
"He has spells, and good days racing around and he usually crashes. He wants to be doing more than he can, but it's worth seeing it even if he is tired the next day."
While on holiday, Angus paid a visit to his pre-school and tried one of his favourite pastimes, the swing, with best friend Jack Gallie.
While doctors have not changed Angus' initial prognosis, Mrs Beaton is keeping her chin up about the fact his chemotherapy treatments have become less frequent, at every third week.
Mr and Mrs Beaton are hoping to get to the stage where their son can be home for a week at a time before returning back to Christchurch hospital for treatments and his eventual radiation therapy in September.
To prove they are serious about coming home, the family has been looking at rental property after selling their Arrowtown home in May.
For older sister Kate, this is the most exciting news.
"She would love to be back down, she has been so good here pottering around. She doesn't want to be apart from her mother too long."
If a positive has come from Angus' diagnosis, it would have to be the strong bond he and his father have made, she said.
"Gordon is definitely the one Angus wants to be around at the moment. It is something to do with his father being this strong man I think.
"It has been quite a nice stage for them, they've bonded and it has been quite special to see."
Mrs Beaton said she has also been making herself useful at the hospital when new mothers and fathers come in who have received some of the hardest news a parent can.
"Well I am an old timer here now, and it is nice to be able to talk to others coming back in to make them feel like the whole idea of it all is normal.
"Everyone gets scared, coming through those doors it freaks everyone out.
"You always think it will be someone else," she said.
While keeping her feet on the ground, the pre-school teacher is not expecting startling news in either direction from doctors next week.
"Things feel a wee bit more stable. It is such an unknown thing."
