"Data can help us understand behaviours in a way that traditional research can't," said Frerk.
A recent report estimated a staggering 25 billion IoT devices in the world by 2020. PwC believes it will soon become a multi-trillion dollar industry.
Frerk urged the gathered business leaders to be "aware of new technologies that exist and how they can help you".
"It's not about when you need to do it, but when you should start," he said.
Russell Craig, Microsoft New Zealand's national technology officer, said businesses here are already investing heavily in IoT technology, in a country where the desire for innovative technology has always been very strong.
He is excited by the innovation particularly in the primary sector, as well as transport.
Samantha Ramlu, managing director and co-founder of creative innovations agency Method, said it was important for businesses to work out how they can meaningfully use the technology to improve their business.
While teller-less supermarkets might not seem realistic for New Zealanders today, the technology will "definitely" arrive here, and in the meantime, companies should be looking at smaller ways of utilising the IoT, Ramlu said.
