''I have got posters on my wall of Rio and I want to get there,'' Bloxham told the Otago Daily Times while in Dunedin for the hammer-throwing festival last weekend.
The standard to get to an Olympic Games is high but his rapid progress over the past 12 months suggests it is possible.
Bloxham (17), of Auckland, holds three New Zealand junior records - 79.74m with the 5kg hammer, 69.11m with 6kg and 61.77m with 7kg.
''Making the world championships last year has made me want to strive for more,'' he said.
His coach, Didier Poppe, rates his potential.
''We hope that he will reproduce with the 7.26kg [senior] hammer the same distance he is getting with the 5kg [youth] hammer,'' Poppe said.
''At the moment everything looks optimistic but there is such a lot of work to do to manage a 7.26kg implement. You never know if he will succeed or not.''
Poppe feels the Rio de Janeiro Olympics will come a bit early for Bloxham.
''But he could qualify. We will just have to wait and see.''
Bloxham intends to put his energies into the 6kg implement this season and qualify for next year's world junior championships in Oregon in the United States.
''I want a medal over there,'' Bloxham said.
''I wasn't happy with my 11th place at the world youth championships in the Ukraine this year. That performance has made me strive for it more. I want big distances with the 6kg shot.''
Athletics New Zealand has made it harder and has raised the qualifying mark from 67.5kg to 73.5kg for the A standard.
But the 6m difference has not deterred Bloxham.
He reduced the gap to 4m with his record-breaking throw of 69.11m at the Caledonian Ground on Saturday.
''I put chalk down and it gave me more grip and made it easier to get more speed off the back,'' Bloxham said.
''Once I let it go, I knew it was better than the 67.11m I'd thrown earlier. When I heard it was over 69m, I was really happy.''
The B standard for the Commonwealth Games at Glasgow with the 7kg implement is 67.5m. His best is only 61.77m but Bloxham has lifted his standard over the past 12 months.
''My speed and balance in th circle has got better. You can't go fast if you're not balanced.''
Bloxham has inherited athletics genes from his parents, Donna and Barry.
''Mum was a good 400m runner until she had to give up because of a stingray bite that affected the ligaments in her toe,'' Bloxham said.
''Dad wasn't an athlete but he was a milkman and used to push trolleys up and down hills. I've got my strength from him.''
