Stewart, who played 18 times for the Kiwis in the 1980s, admitted the force he'd used to tackle Ms Connor was excessive.
Convictions weren't recorded, but the former NRL star will be required to pay up to $2000 if he breaches the bond.
There has been an ongoing feud between Ms Connor, Stewart and ex-wife Victoria.
Their clashes began in 2013 when Mrs Stewart faced court over allegedly assaulting Ms Connor, the Gold Coast Bulletin reports.
During that hearing the court was told that Mrs Stewart had scratched three words - 'sl**, wh**e and hooker' - into Ms Connor's car which was parked at a resort where she had been having an affair with the NRL star.
But Mrs Stewart was found not guilty over the incident, with the Magistrate ruling she had been provoked.
That incident was followed by Ms Connor being charged with stalking Mrs Stewart from December 1, 2013 to April 15, 2014. The charges were later dropped by police.
