Otago SMEs that took part in the survey were the least connected, with 6 per cent reporting they were hooked up to the much faster internet network.
Of the SMEs surveyed, 63 per cent said UFB would have a positive impact on their business while 30 per cent did not think it would have any effect.
"It's encouraging to see the majority of small-to-medium business owners in New Zealand are grasping the potential for ultra-fast broadband to transform their businesses," MYOB's James Scollay said.
"UFB will revolutionise the way business owners use business management tools, including cloud accounting. It will no doubt result in increased productivity, cost reductions and, in turn, an SME sector that can compete more effectively on both a local and global scale," he said.
A higher proportion of SMEs that had UFB were satisfied with the cost of their internet plan than those that did not.
Just over 40 per cent of those with UFB were satisfied with the cost of their internet plan, compared with 32 per cent of those not on fibre.
Of those on UFB, 22 per cent were still dissatisfied with their connectivity, while 51 per cent expressed satisfaction with their fibre internet. The remaining 26 per cent were neither satisfied nor dissatisfied.
