He is Tobias Devereux - an 10-year-old Kaikorai Primary School pupil who has been spending four hours a week at Kavanagh College this year, studying NCEA level 1 maths.
Last month, he sat the NCEA level 1 maths exam and now he is awaiting results.
To say the least, he is a maths whizz, but the extraordinary thing about Tobias is that he outdid his fellow Kavanagh pupils, finishing top of the year 11 class, and took great pride in crossing the stage at the college's senior prizegiving recently.
Tobias said class life among 16-year-olds at a secondary school was quite different from that of his usual primary environment.
''Sometimes it feels a little odd. Mostly because they are all in uniform and I'm not.
''My feet reach the floor on the big chairs - just.''
His success at Kavanagh is just one of many achievements he has made this year.
He finished in the top 0.3% of the Australian Maths Competition, was in the top 100 year 9 pupils in the New Zealand Junior Mathematics Competition, achieved 24/25 in the 2014 Problem Challenge, achieved high distinction (top 1%) in the International Competitions and Assessments for Schools (ICAS) maths and science examinations, distinction in ICAS English (top 2%), ICAS spelling (top 3%), ICAS computer skills (top 5%), honours in grade 3 jazz dance exam, grade 4 ballet exam and level 4 hip-hop exam.
His teacher, Linda Martin, said it was fair to say Tobias is an all-rounder.
''He's at the top end of the scale in all areas of the curriculum.''
Mrs Martin said Tobias was placed in her year 5 and 6 class three years ago as a year 4 pupil because he was so far ahead of his year 4 classmates.
''His parents had to provide a maths tutor for him last year, because he was so far beyond what we could provide for him.
''We wouldn't have managed otherwise.''
Kavanagh College principal Tracy O'Brien said having primary school pupils learning at such an accelerated level was rare.
''It's not unheard of, but it certainly is special when you see young people that are well advanced in any subject. It is a pretty outstanding feat and he promises a lot for the future.''
Mr O'Brien expected Tobias would get good results in level 1 maths, and would ''be in the frame to take on the level 2 course quite comfortably''.
''The early signs are he is a very promising scholar, and particularly with his maths, he will be something of a protege for sure in the future.
''He's certainly got some real smarts.''
Tobias will study full-time at Kavanagh next year as a year 7 pupil, and plans to study NCEA level 2 maths - which he hopes to top again.
He also has aspirations of studying computer science at university, with a view to becoming a programmer.
Who knows, he may achieve that goal before most people his age are finished secondary school?
