Police are investigating three fresh complaints in connection to "historical incidents" at the notorious bar in central Christchurch.
Brothers Danny and Roberto Jaz were convicted and jailed in August last year for committing 69 offences including rape, sexual violation, indecent assault, stupefying, disabling, making intimate recordings of women without their knowledge or consent, and supplying illicit drugs.
The pair used their positions at family businesses, including Mama Hooch and restaurant Venuiti, both in Colombo St, to commit the acts.
As bar managers, they preyed on patrons and waitresses, drugging and sexually assaulting 17 young women between 2015 and 2018.
Roberto was jailed for 17 years, with a minimum non-parole period of 8.5 years when sentenced at the Christchurch District Court on August 24 last year. Older brother Danny was given 16.5 years, with no parole available until at least eight years had been served.
Both are appealing their convictions, but it's unclear on what grounds.
The sentencings followed a nine-week judge-alone trial, where it emerged the brothers had targeted 32 people, mainly young women aged between 18 and 24.
"Statistically, one in three or four sexual assault cases actually get reported to police," she said.
"So the chances were incredibly high that there were other women that were impacted by these men that weren't captured in the trial.
"It's awesome to see other women coming forward, whether it was seeing the trial, or something that [has] compelled them to do it, it's amazing they've felt that they're able to."
Brown recounted to the court last year "picking up the fragments of her life" after she was drugged and sexually violated in 2017
Waiving her rights to name suppression, she was one of several survivors who delivered powerful impact statements as the Jaz brothers learned their fate.
Although conceding it would be speculation, she said there could be more survivors out there who had been affected.
"Reporting isn't everyone's journey of healing, and some women won't and that's okay. But I would definitely say there could be more."
She added she felt proud that others had "found their voice" to the point where they felt they could report their experiences to police.
"If anyone else is suffering with this, and tossing up with the idea of reporting or not reporting, just understand it's absolutely your personal decision.
"I hope these women are looking after themselves and doing what's right for them."
Victims advocate Ruth Money also said further complaints materialising was "sadly not surprising".
"It's very rare that we will see this level of offending just being that first group of survivors who came forward," she said.
Money acknowledged all "the brave ladies" who had taken the brothers through the justice system and the new complainants coming forward.
"It's actually a catch-22 situation," she said.
"Any survivor is triggered by the coverage of something that is similar to what they have experienced.
"The trial itself was triggering for a number of people, particularly those who were the survivors who had disclosed at the time, but also these new ones who hadn't disclosed yet.
"But what it says is that 'you're not alone'."
Money said she took solace in the fact the new survivors had been brave enough to endure the justice process for something that had already been through the courts.
Both venues have since closed, and the company, Jaz Holdings Limited, was put into liquidation in early August last year.
A police spokesperson said since the Operation Sinatra trial last year, they had received three complaints relating to historic incidents at Mama Hooch.
"Police won't comment on the specifics of the complaints but they are continuing to investigate."
