"My brothers are at Yale so I knew to talk to the coaches to get in there. I started talking to them by email. It was more or less my gateway into Harvard. You still have to get in with grades, but the rowing helps because the coaches will put in a good word for you."
His rowing career also helped with his choice of university as Harvard offered training in singles and doubles, Daniel said.
"We visited my brothers at Yale two years ago and I toured Harvard then. I think it's really cool there but I haven't been in winter so I don't know what that's going to be like.
"I met up with the coaches when I was there and sat in on quite a few lectures. I think the campus is great ..."
At this stage, Daniel said he was looking at studying engineering but he had not yet made up his mind. He still had a few months to choose as he left for Massachusetts in August.
Daniel said his parents would cope with him leaving as they had already been through his two brothers going to Yale and his oldest brother moving to Australia.
Mother Kathryn Sharplin agreed. "I'm a mum so I will miss him, but it's a good adventure. I'm proud of all of my boys, obviously they are bright and hard workers."
Ms Sharplin said she would visit Daniel and bring him back once or twice.
In December, the Bay of Plenty Times published a story about Otumoetai College student Emma Dwight being accepted into Harvard. Emma was considering studying science at the prestigious university.
