O'Reilly says that more work needs to be done to ensure New Zealand is providing a world-class business environment, with the career advancement opportunities and pay-grade top-tier talent expects.
"We can't just rely on the idea that New Zealand is clean and green, a long way away and a pleasant place to live," he said. "That's not enough to attract them.
"We need to offer world-class careers and a world class income - too often we try to get away with paying less because we're a nice place to live - but a lot of other places have those same advantages.
"We need to focus that we're at the top of our game when it comes to attracting top talent and not just rely on the snow-covered mountains and babbling brooks to pull us through.
"If we're going to get truly sophisticated on the global stage, we need some truly sophisticated global business people coming to New Zealand more often to assist, lead and play their part in taking us to the next level."
One source which New Zealand businesses are failing to effectively capitalise on is expat Kiwis returning home. O'Reilly says that for many, their lack of recent experience in the domestic business environment can actually be a positive.
"Far too many New Zealand businesses have 'not invented here' syndrome where they overlook people without New Zealand business experience.
"We need to make sure that we have really smart global business people running smart global businesses from here in New Zealand."
