The technology behind AXA Australia's platform, one of the key reasons why the competition regulator blocked NAB's bid for the company, can be accessed by anyone in the market, according to one technology provider.

This week the Australian Competition and Consumer Commission (ACCC) blocked NAB's bid for AXA Australia because it would give NAB/MLC an uncompetitive position in the investment platform market.

The ACCC said it favours the AMP bid because the financial services firm does not have a competing platform.

However, Ian Mathieson, chief executive at DST Global Solutions Australia and New Zealand, which owns the technology behind the AXA platform, Wealth.net, said NAB could buy a licence to the same technology.

"I'm not sure I fully understand the sensitivities that Graeme Samuel [ACCC chair] is espousing because the technology that he might be referring to is available to anybody," he said.

"In his deliberations that he spoke about was third party technology and not owned by AXA - NAB could turn around tomorrow and buy our a licence for the technology."

DST Global Solutions' local offices have been inundated with calls since the ACCC decision.

"Since that time, we've had calls from a number of people and one of our relationship managers has just told me that someone wants to have a chat to us about the technology soon," he said.
