Background and Appointment
In May 2020, Rachel Wansbrough—then known by her maiden name Lamberth—was appointed payroll manager at Isaac Construction, a Christchurch‑based building firm. The role granted her full access to the company’s payroll and debtor systems, allowing her to initiate payments, issue credits, and view financial data. Although she sometimes worked from home, she maintained personal accounts with seven different banks, a factor that later facilitated the diversion of funds. Her position of trust placed her in a powerful gate‑keeping position over the company’s money flows.
First Fraudulent Refund – April 2021
The dishonest conduct began in April 2021 when Wansbrough emailed the company’s financial administrator, requesting a $718 refund be issued to a customer. She attached an image of a Bank of New Zealand (BNZ) account number, which was in fact her own. The administrator, believing the request to be genuine, processed the refund, directing the money into Wansbrough’s personal BNZ account. This initial transaction set a pattern of using fabricated documentation to siphon company funds.
Second Refund – May 2022
A year later, in May 2022, Wansbrough repeated the tactic. She emailed the same administrator, this time claiming a double payment required a $3,510 refund. Supporting the request, she supplied an image of a Kiwibank account number that belonged to her. The administrator complied, transferring the sum to her Kiwibank account. By now, two separate fraudulent refunds had totaled over $4,200, illustrating a growing confidence in her ability to deceive internal controls.
Fabricated Client Email – September 2023
In September 2023, the scheme became more elaborate. Wansbrough forwarded a fabricated email to the company’s administration manager, purporting to be from a client company. The false correspondence claimed that a client had been overpaid by $11,842 and requested a refund be issued. She attached details of her SBS Bank account as the destination for the funds. The administration manager, trusting the apparent client communication, processed the refund, sending the money to Wansbrough’s SBS account. This transaction marked the largest single theft to date.
Fake Invoice – March 2024
The final payroll‑related fraud occurred in March 2024. Wansbrough issued a credit note for $9,479, asserting that the amount had been erroneously paid by a client company. To substantiate the claim, she produced a counterfeit invoice and directed the repayment to her ANZ account. The company’s accounts payable team, relying on the falsified documentation, transferred the sum. By July 2024, eight such transactions had collectively drained $56,620 from Isaac Construction.
Impact on Isaac Construction
The cumulative effect of these eight fraudulent refunds was a direct loss of $56,620 to the company. However, because the funds were initially paid out as refunds or credits and later recovered through the fraudulent MSD wage‑subsidy scheme (see below), the judge determined the total loss attributable to Wansbrough’s actions against Isaac Construction to be $119,000. This figure reflects both the stolen amount and the subsequent financial strain placed on the business as it sought to reclaim the misappropriated funds.
Covid‑19 Wage‑Subsidy Fraud
Between April 2022 and May 2023, Wansbrough abused her access to company data to submit multiple Covid‑19 support applications to the Ministry of Social Development (MSD). Posing as Isaac Construction, she claimed wage subsidies for hundreds of employees, providing her personal bank account details as the company’s receiving account. The MSD disbursed a total of $131,000 in response to these applications. Of this sum, $69,000 was deposited directly into Wansbrough’s accounts, while the remainder was initially paid to the company and later transferred to her through the fraudulent refund mechanism described earlier. The judge emphasized that this part of the offending compounded the breach of trust, as it exploited a government relief program intended to support workers during a pandemic.
Judicial Findings and Sentencing Considerations
Judge Tony Couch characterized the offending as serious, noting that in each instance Wansbrough forged documents to create deception. He described her use of falsified paperwork as prolific and a profound violation of the trust placed in her by her employer and the state. The judge stressed that all of the offending was clearly premeditated, indicating a deliberate and sustained course of criminal conduct rather than isolated lapses. Starting from a baseline sentence of three years and four months’ imprisonment, the judge applied reductions for Wansbrough’s guilty pleas, evidence of rehabilitative efforts, and demonstrated remorse. These mitigating factors contributed to a substantially reduced custodial term.
Sentence and Reparation Orders
After accounting for the discounts, Judge Couch sentenced Rachel Wansbrough to 12 months of home detention, allowing her to serve the term within the community under strict monitoring conditions. In addition, the court ordered her to pay reparations totaling $188,000: $119,000 to Isaac Construction to compensate for the loss suffered by the company, and $69,000 to the Ministry of Social Development to reimburse the fraudulently obtained wage‑subsidy funds. The reparation amounts aim to restore, as far as possible, the financial position of the victims and to hold Wansbrough accountable for the monetary harm caused.
Conclusion and Broader Implications
The case of Rachel Wansbrough serves as a stark reminder of the dangers inherent in granting unrestricted access to financial systems without adequate oversight. Her ability to manipulate payroll, debtor, and government subsidy processes over an extended period underscores the need for robust internal controls, segregation of duties, and regular auditing of financial transactions. Employers should verify the authenticity of refund requests and subsidy claims through independent channels, and government agencies ought to implement stricter validation of applicant banking details. While the home‑detention sentence reflects the court’s consideration of Wansbrough’s remorse and rehabilitative prospects, the substantial reparation orders seek to redress the financial damage inflicted on both a private enterprise and a public relief program. The prosecution and sentencing highlight New Zealand’s commitment to addressing fraud that undermines trust in both corporate and governmental institutions.
