The 16-year-old spent seven months creating his remote-controlled iPod Super Dock which allows him to connect his iPod to large sound systems or computers - all because there was no affordable equivalent in electronics stores.
The device won him first-equal place in the 2008 New Zealand Bright Sparks HiTech Competition in October.
Now it has won him one of two Royal Society of New Zealand travel awards at the Genesis Energy Realise the Dream Competition, which will pay for him to represent New Zealand at the International Science and Technology Fair in Taipei next February.
He will be joined by Mt Roskill Grammar School pupil Abhilash Kamineni (16) with his project, a multipurpose robotic arm.
Secondary pupils from 25 countries will participate in the event.
Ben said it was a "once in a lifetime" opportunity to display his invention on the world stage.
"There's no stage bigger for me. This is an amazing opportunity to show my product to the world."
He was shocked when he won the award because the competition was of a high calibre, he said.
"I wasn't expecting to win anything big like this. It makes me see things in a slightly different light. Who knows what I'm capable of now?"
Other projects at the event included rocket performance research, a touch-screen clock, a home-made spectrometer and a wood-powered engine.
