- The friend, Petronella Laatz, did not actually own the shares at the time of the sale and later used the money to acquire them herself.
- The Mienies were misled into believing they could recover their investment through a notice‑to‑leave clause, but Laatz never repaid any funds.
- Laatz pleaded guilty to obtaining by deception and was sentenced to 12 months’ home detention, with a reparation order requiring $50 per week from her KiwiSaver and wages.
- The victims view the repayment terms as inadequate, feeling that their hard‑earned savings are unlikely to be recovered in their lifetime.
- The case underscores the importance of verifying ownership and financial details, even when dealing with long‑standing friends, and highlights how trust can be exploited in financial fraud.
Background and Motivation
Carlien Mienie, a South African immigrant, had spent years working long, physically demanding days on a dairy farm near Taupō. She and her husband, Carel, had emigrated to New Zealand seeking a safer life away from the crime and danger they experienced in their home country. The relentless calving work left Carlien eager for a change, and she hoped to leave the farm behind for a less strenuous livelihood that would also allow her to enjoy a more comfortable lifestyle.
The Friendship and Proposal
Through their South African community, the Mienies had developed a close, multi‑year friendship with Petronella Laatz, known locally as “Ronel.” Laatz approached Carlien in May 2023 with an enticing proposition: she claimed to own shares in Montevideo Ltd, a business that operated a café in Taupō, and offered to sell 40 percent of those shares. Laatz painted a rosy picture of the café’s success, mentioning her recent purchase of a new BMW and suggesting that the Mienies could join her in running the business, thereby ending Carlien’s farm work and allowing her to “dress up nicely.”
The Investment Terms and Payment
The agreed price for the 40 percent stake was $150,000. Although Carlien’s husband was initially hesitant, she convinced him to proceed, emphasizing the trust they placed in their long‑time friend. Acting on Laatz’s request, the Mienies transferred the money directly into her private bank account over three days. Laatz supplied a Share Purchase Agreement dated 31 May 2023, which stated that she was the seller and the sole owner of 100 percent of Montevideo’s shares.
Due Diligence Oversight
Despite the substantial sum involved, Carlien admitted she never verified Laatz’s ownership claim. She did not think to check the Companies Office register to confirm who held the shares or who served as directors. The Mienies relied entirely on Laatz’s word and their friendship, assuming that because they had known her for many years, her representations were truthful. This lack of independent verification proved costly.
Realisation of the Fraud
Months passed with no communication or returns from the investment. When the Mienies later wanted to explore another opportunity, they referred to a signed agreement that allowed any party to give notice of intent to leave the business and receive a refund of their contribution. Laatz then claimed the café was underperforming, said she intended to sell it, and promised to repay the money. In reality, after receiving the Mienies’ funds, Laatz used the money to purchase shares in Montevideo herself, becoming a majority shareholder in October 2023. The Mienies received no repayment, and Laatz eventually sold the business without giving them any proceeds.
Police Investigation and Charge
The Mienies reported the matter to police, who investigated and discovered that Laatz had never owned the shares she sold. She was charged with obtaining by deception. During police questioning, Laatz told investigators that the Mienies “knew she was not a full shareholder,” a statement contradicted by the Share Purchase Agreement she had provided. The Companies Office register confirmed that Laatz was only listed as a shareholder after the Mienies’ payment, confirming that the funds she received facilitated her acquisition of the stake.
Court Proceedings and Sentencing
In the Taupō District Court, Laatz pleaded guilty. Judge Thomas Ingram acknowledged the profound betrayal of trust, noting that the Mienies had accumulated the money through years of arduous farm work. He stated that Laatz had taken advantage of a long‑standing friendship and described the offence as “callous.” The judge initially considered a starting point of three and a half years’ imprisonment but applied discounts for her guilty plea, first‑time offender status, and willingness to pay reparation. The final sentence was 12 months’ home detention, accompanied by a reparation order requiring $10,000 to be taken from Laatz’s KiwiSaver and the balance paid at $50 per week.
Reparation Order and Victim Reaction
Carlien Mienie expressed frustration with the reparation arrangement, describing the $50‑weekly payment as “absurd” given the size of the loss. She had hoped the court process would enable them to reclaim their life savings, but the slow repayment schedule makes full recovery unlikely within their lifetime. The Mienies emphasized that the money represented the proceeds of hard, physical labour and that its loss has left them financially strained at an age when rebuilding such savings is difficult. Laatz declined to comment on the matter through her lawyer.
Lessons and Reflection
This case serves as a stark reminder that trust, while valuable, should not replace basic due diligence in financial transactions. Even long‑term friendships can be exploited, and individuals should verify ownership, examine corporate records, and seek independent advice before transferring significant sums. The Mienies’ experience highlights the emotional and financial toll of deception, especially when victims have invested their life‑savings in pursuit of a better, safer future. Moving forward, greater vigilance and a willingness to question seemingly generous offers can help prevent similar losses.
