The revelation came hours after Veitch announced his resignation from TVNZ where he was a sports presenter on One News and host of the sports quiz show a Game of Two Halves, and Radio Sport.
Yesterday the Sensible Sentencing Trust said the alleged attack was chilling and Veitch's high-profile in the community was not an excuse or a reason for leniency.
"He must go to prison," a spokesman said.
However, others within the legal fraternity said if Veitch was charged and convicted he may avoid a prison term under the terms of the Sentencing Act, 2002.
The Act said when sentencing, the courts must take into account any financial offer of amends made by the offender to the victim.
Police confirmed yesterday Kristin Dunne-Powell had lodged a formal complaint of assault over a 2006 incident where Veitch allegedly kicked her so hard he broke her back in four places.
Veitch was reported to have paid Ms Dunne-Powell up to $170,000 in compensation and hush money after they apparently agreed to say she was hurt in a fall on the stairs.
The complaint to police by Ms Dunne-Powell removed a major hurdle in the police investigation into the alleged assault by Veitch.
Three police officers have been working on the case for the past week.
Veitch will be paid out three months' notice at TVNZ and one month at The Radio Network (TRN), with both employers yesterday paying tribute to his broadcasting talent.
TVNZ chief executive Rick Ellis said yesterday the resignation was immediate.
While TVNZ had discussed options with Veitch and his lawyers, Mr Ellis would not say if Veitch had to either resign, or be sacked.
"It is fair to say Tony has taken the decision to resign off his own bat," Mr Ellis told a media conference yesterday.
Had Veitch not resigned, disciplinary action would have started, Mr Ellis said.
The incident was very embarrassing for the state channel, he said.
TVNZ had been "absolutely inundated" with letters, emails and phonecalls from the public showing extreme disappointment and disapproval.
Announcing his resignation Veitch, who had worked for TVNZ for around 13 years, said he needed to take stock of his life and spend time with his family.
"I would ask that people now respect the agreement Kristin and I made to keep our personal affairs private," he said.
"At all times I have been honest with my employers and at all times I have tried to do the right thing for everyone.
"There have been a lot of statements made that are untrue which make it untenable now for me to continue in my current roles with TVNZ and the Radio Network."
National Collective of Independent Women's Refuges chief executive Heather Henare, said Veitch was wise to resign.
"What Tony understands as being the right thing to say and do is still not in touch with complete reality and accepting full and unconditional responsibility."
