"There are some issues around the questions of how the school terms might fit but they could be adjusted."
Dunne said he also understood the change could impact the business cycle but he didn't think any of the issue were "insurmountable".
"That's transition. These are things that we could get over if we decided to make a change."
Since speaking out, Dunne said he had received only positive feedback.
"The comments that I have seen on Twitter, Facebook and just in general emails... I haven't had one negative one yet."
But Business New Zealand CEO Phil O'Reilly says while he likes the idea of taking holiday at the hottest time of the year, the practicality was a "problem".
"For me, as a human being, it's a nice idea.
"As a personal thought, I suspect most New Zealanders would say 'Yeah, I'd like to be taking February off, because the weather's better.'"
But as a business representative, the problems associated would be two-fold, he said.
The first would be the fact that nowhere else takes their holidays in February.
"We'd be on holiday and all of our customers would be ringing us up saying 'where are you?'"
We'd be out of step with what's happening with our trading partners.
Secondly, the "sunk costs" of the change - such as changing the school year - would be big.
"It's big, I don't know how you'd define it but it's multi-billions. Big numbers.
"Those two things along would make you say 'It's probably too hard.'"
O'Reilly also noted that, as we move away from the traditional factory-based model towards a more service and knowledge-based economy, people have more choice about when they want to take their holidays anyway.
"The [thing] that is insurmountable is that nobody else in the world is on holiday in February.
"We don't get to tell the world what to do."
However, this sentiment wasn't reflected in a WeatherWatch poll that ran last year, said head analyst Philip Duncan.
The poll asked readers to choose when their preference for holidays would be.
Twenty-eight per cent wanted to leave the holidays as they were, 17 per cent wanted to take their holiday in January and 55 per cent said they wanted to take the time off in February.
"It does make sense if you think about it. December is very much like spring, a lot of meteorologists believe that summer doesn't officially start until the longest day of the year just before Christmas.
"We are almost at the wrong end of the season."
