"The element of fear that was in the business community about a Labour/Green Government, I think, is well gone," he said.
"Businesses that are good businesses will still be able to do well under everything I've seen from the Labour party."
He said issues could arise with tax complexity under Labour, but the business community also faces problems under National led Governments.
"Business doesn't necessarily do better under National led Governments," he said.
Productivity was the biggest issue facing the business community in the country and growth was nominal without it, Campbell said.
Campbell said the current Government had provided economic stability but a lack of growth.
"There is an increasing recognition among the business community and the wider community that things have got a little stale," he said.
"If I can use a word from a previous National Prime Minister, maybe we need to be a bit more aspirational."
Campbell described Bill English as a very capable economic manager and one of New Zealand's best Finance Ministers, but said he had not had a chance to prove what kind of Prime Minister he would be.
"We haven't really seen enough yet to know if he would be a very good Prime Minister or not, and I guess in the end he may not get the opportunity to show that."
Inequality was another big issue for Campbell.
"The people who are at the wrong end of the inequality really have genuine social and financial needs that are not being met under the current system," he said.
Campbell said the Government needed to provide additional income support at the base.
Asked his opinion on the Finance Minister Steven Joyce and his Labour counterpart Grant Robertson, Campbell said Robertson might be less experienced but that was not necessarily a bad thing.
"[Robertson] is probably more inclined to think and research issues than Steven might be," he said.
"You might say you don't want people to learn on the job, but I always have. I don't see why Grant couldn't do that as well."
The Herald's Mood of the Boardroom Election Survey will be published tomorrow. In an event streamed on nzherald.co.nz, National's Steven Joyce and Labour's Grant Robertson will debate the survey results.
