The Bethlehem College pupil was overwhelmed when he heard the news.
"I was pretty surprised there were so many names in the bag and when I heard the news I was thinking, 'oh my gosh'," Oliver said.
"I like playing golf. It is my second favourite sport after tennis and I wanted to play (in the Junior Tiger). I looked it up on the website after I heard the radio."
Oliver is taking his father Mike to Disneyland with him - some time in July around his 10th birthday.
Mike says he is looking forward to spending some quality time with his son, as he works Monday to Friday in Christchurch as part of the rebuilding team.
The Junior Tiger concept, which has been a great success since it was introduced in 2009, is geared to get more kids playing golf at both a competitive and participant level.
The most obvious success story has been teen sensation Lydia Ko.
Three years ago Ko won the 12-14 age division of the Junior Tiger final as a 12-year-old and is now the World No1 amateur.
