Mr Raimond was grilled about the outcome of the fact finding mission at budget estimates hearings on Thursday.
He discovered that only local MPs and local councils had been briefed about the motorway’s route, shortly before it was announced.
“What was your final conclusion then about how Daryl Maguire got that info, given he wasn’t a local MP?” One Nation MP Mark Latham asked.
“I wouldn’t wish to speculate,” Mr Raimond responded. “My job isn’t to speculate, it was to check on the facts of the matter and I checked”.
He said there was a “lot of information in the public domain” about the corridor before it was announced but conceded specific details of the route through individual properties was kept “very tight”.
“No developer should know precisely where the route goes before the public knows?” asked Labor MLC John Graham.
“No, we are certainly at great pains not to reveal detailed maps,” Mr Raimond said.
Mr Raimond rejected developer Country Garden’s claim to the Herald that it was able to figure out the route from a map published by Transport for NSW in 2015, which showed a purple shaded “study area”, known by bureaucrats as the “purple haze” map.
“They [Country Garden] could not have relied on that 2015 purple haze to draw a very specific line through the corner of their property, could they? That is impossible?” Mr Graham asked.
“Yes, certainly the 2015 consultation was about a study area – not a particular route,” Mr Raimond said.
A spokesperson for Country Garden, now known as Risland Australia, said:
“No employees of Country Garden received information that was not publicly available about the M9 corridor route or had meetings with Transport for NSW specific to the [outer Sydney orbital]/M9 corridor. Information was available from 2015, and has been evolving since this time in the public domain, including from the Greater Sydney Commission process in 2017.”
The spokesperson has previously denied Daryl Maguire had any involvement with the purchase of the site.
