A Herald investigation can reveal:
He failed to provide appraisals for homes supported by comparative sales data, provide necessary documentation to sellers, or set out how the properties would be marketed when clients signed agency agreements.
When bringing a customer to view a client's property, Drever told the seller words to the effect of, "Shut your mouth, don't say a word, they're my clients".
In an earlier finding, the Complaints Assessment Committee found he had likely secured a longer settlement period for a fourth complainant in return for her withdrawing a complaint about him, which was labelled "tantamount to blackmail". This matter is under appeal.
Wendy Lowe, who enlisted Drever to sell her home in 2013 and is one of the three misconduct complainants, believed he hadn't changed and should lose his license.
"He is in a registered occupation with a code of practice. People trust him. You shouldn't be able to have this job if you've proven you're unworthy of it."
Drever's disciplinary history stretches back to November 2011 and includes seven unsatisfactory conduct findings and two of misconduct.
He faced a police charge in 2014 after depositing more than $15,000 of client marketing funds into his own account. The criminal charge was dropped when he repaid the money.
A prosecutor described Drever's actions as "an appalling lack of judgment" and the REAA unsuccessfully sought an interim suspension of his licence.
Drever, 33, later joined Ray White's Pure Realty franchise in Kelston and became one of the company's top international salespeople. But he was dumped last year after a misconduct finding before being employed by Harcourts' New Lynn office.
He was dropped by Harcourts after the Weekend Herald published an account of his previous offending.
In a tearful interview last year, Drever blamed the sheer volume of sales work for his repeated breaches, but said lucrative commission money was only a "secondary focus" as he cared for his terminally ill father.
He also said he knew of countless cases of unethical behaviour among his peers.
In a statement yesterday, Drever accepted he had made mistakes and that it would take time to rebuild his reputation and public confidence in his ability to work as a real estate agent.
RE/MAX director Chris Chapman said he could not comment on the latest disciplinary hearing outcome as he was yet to see it. Drever left the network's Hedgman Realty in October 2013.
Chapman added that the "disciplinary tribunal may order compensation to a complainant if appropriate to the circumstances".
Australia-based Ray White spokeswoman Lisa Pennell said Ray White elected to end the relationship with Drever "because of the misconduct findings made by the REAA".
Harcourts chief executive Chris Kennedy confirmed the company had ended its dealings with Drever.
Drever will learn his fate at a penalty hearing in October.
The findings:
Aug 2016
Joint misconduct finding
35 Archibald Rd, Kelston
Marie van Eijk sold her Kelston home through Aaron Drever in August 2013 for $441,000 to a property investment company.
The property was subsequently re-listed by Drever when he went to Ray White and on-sold by one of his colleagues. It was sold in December that year for $585,000 after undergoing significant renovation costing $106,000.
Investigators found Drever had failed to provide an appraisal supported by comparable sales data or explain how the property would be marketed when his client signed an agency agreement.
Eijk, a retired 68-year-old from the Cook Islands, told the Herald Drever was a "fast talker - very good with words".
She believed he should lose his licence.
"I would be very disappointed if he goes back to practice."
Awaiting penalty.
Aug 2016
Joint misconduct finding
99 Grassmere Rd, Henderson Valley
David Deyermond sold his Henderson Valley home through Drever in 2013 for $705,000.
Investigators found Drever had failed to provide an appraisal supported by comparable sales data or explain how the property would be marketed when his client signed an agency agreement.
When bringing clients to view the property, Drever also told Deyermond words to the effect of, "Shut your mouth, don't say a word, they're my clients".
Deyermond, 66, told the Herald he could not understand how Drever was allowed to continue practising as his track record worsened.
"He should be banned for life from holding a licence for real estate to save any further hurt or stress on people who place their properties to sell in his hands."
Awaiting penalty.
Aug 2016
Joint misconduct finding
52B James Laurie St, Henderson
Wendy Lowe enlisted Drever to sell her Henderson home in 2013 but later cancelled the agreement and switched agencies.
Investigators found Drever failed to provide an appraisal supported by comparable sales data or explain how the property would be marketed when his client signed an agency agreement.
Lowe, 58, told the Herald she was stunned to learn that thousands of dollars in marketing funds she paid to Drever had been deposited into his own account, rather than the RE/MAX agency's trust account.
She eventually cancelled the agreement and believed Drever hadn't changed.
Awaiting penalty.
