For firms that deal business-to-business, the survey found LinkedIn is the favoured tool. In the wider commercial world, however, retailers such as the Countdown supermarket chain tend towards Facebook, which has broader reach.
Vaughn Davis, who runs ad agency The Goat Farm, says the highly visible social media activities of big businesses such as Air NZ and the retail banks can give a false impression of how widely the tools are used.
"I suspect you don't have to go very far down the business tree to find many small business owners are still to see the benefits."
Large organisations have the luxury of being able to dedicate staff to creating a social media presence. But that can also be a handicap, says Davis.
"If you're a three-person wood-fired pizza company in Kumeu and you're absolutely committed to making great pizzas, it's easy for all three of you to be honest and engaging on social media."
On the other hand, the shipping line with 10,000 employees, five of whom have the job of telling the company story via social media, could struggle for an audience.
"The bigger they are the less likely it is that their social media communicators are going to be fully connected to the heart of what the place is about. The further you get from the heart and vision of the organisation the less potent your social media interactions are going to be."
Social media can give small organisations a disproportionately large voice, and Davis expects businesses that are yet to test the water will eventually be swept up.
Before taking the plunge, Scott says, an organisation needs to know what it wants to say.
"Whether it's social media or any other communications, the first thing is to figure out what the messages are and the market they're intended for. Content comes first and delivery method second."
At the technology companies Concentrate works for, the typical approach is to produce a document that backgrounds a product, service or market segment and publish it on the company website.
A link will then be sent via whatever social media tool or tools - whether Twitter, Facebook, Pinterest, Google+, YouTube or LinkedIn - the company's market pays attention to.
If the bewildering array of social media is off-putting to newcomers, a service such as HootSuite can take care of the publishing process.
"You put the content in and HootSuite manages all the social media channels, so you can broadcast to Facebook, LinkedIn, Twitter, etc, from a single console," Scott says.
Bear in mind, says Davis, that adherents of one channel probably follow the other main ones as well.
"You don't necessarily need to cover all platforms. The trick is to find out where the conversations in your sector or around your brand are largely taking place and that's the place to be."
