A three-day event aiming to address internet issues in New Zealand is in full swing at Auckland's SkyCity Convention Centre.

NetHui kicked off yesterday with a meeting streamed live to 2200 people in more than 25 countries.

Internet NZ Chief Executive Jordan Carter said one of the main discussions is about how the internet can be used to generate business.

"There's making the most of the economic opportunities it presents, so getting small - medium sized businesses online using internet technology to make sales and do business more efficiently."
