Mangatu’s examiner can count the losses but not question the bet

Nearly three years after shareholders first protested, someone independent will finally go through the books on Mangatu Blocks Incorporation’s failed Canadian lamb venture. Māori Land Court Judge Nathan Milner’s decision, dated 15 October, appoints an examining officer to report on the losses. It does not ask that officer to examine whether the committee should have made the bet in the first place.

That is a meaningful step, but only half of one. For any business owner who has sat on a board, the gap is obvious. Counting a loss is accounting. Accountability means asking who made the call, who checked it and what they knew.

A loss nobody can agree on

Start with the number itself. Mangatu puts the loss at $57.2 million. Applicant Marise Lant, acting for a shareholder group holding at least 10% of the incorporation, says it is $86.7 million. That is a $29.5 million disagreement about the size of the hole. Committee chairman Alan Haronga was quick to note the limits of the ruling: “The court did not order an investigation into the decision to enter the venture or into the other matters raised in the application.”

The figure has also drifted. In 2025, a legal analysis of the case described current estimates as “significantly higher than initially disclosed figures”. When the loss keeps growing in the telling, disclosure is part of the problem, not a side issue.

Forest carbon funded a lamb gamble

The venture was the North American Lamb Company, or Nalco, formed in 2018 by merging Canada Sheep and Lamb Farms, owned by Mangatu-controlled Integrated Foods, with Canada Gold. The same 2025 analysis noted Mangatu partly financed it with carbon credits earned by replanting 8,000 hectares of Māori-owned farmland in forestry. Long-dated, low-risk carbon revenue was recycled into a capital-hungry offshore farm-to-plate meat play. Nalco ended in liquidation.

The tail stretched on. Mangatu’s 2024 annual report showed group profit before tax falling to $12.0 million from $33.8 million, with the last $0.9 million of bank guarantees tied to the Canadian investment repaid by December 2024 under a forbearance deal with Canadian lenders.

The excuses the judge didn’t buy

The committee blamed procedural issues, Covid-19, a 2021 Canadian drought, grain prices spiked by the Russia-Ukraine war, higher lamb mortality and rising labour costs. It argued the court should only step in if the whenua itself was at risk. Judge Milner rejected that framing, and his reasoning is the line every governor should read twice: there is “no evidence that expert advice has been sought, considered and steps taken to avoid or mitigate further future losses”.

Droughts and wars happen. A board’s job is to stress-test for them before committing tens of millions offshore. A list of external shocks is not a defence if nobody can show the risks were weighed.

Shareholders already delivered their verdict

Owners have not waited for the court. At the February 2026 AGM they passed a no-confidence vote at 60.12%, demanded disclosure of incorporation money spent fighting the proceedings (66.47%) and backed reimbursing Lant’s costs (63.31%). The same meeting reported $24.3 million profit before tax, $333 million in net assets and $3.54 million returned to owners. The incorporation is not broke. That is precisely why governance, not survival, is the issue. A strong balance sheet can absorb a bad decision without anyone ever having to explain it.

The toolkit is the real weakness

Getting this far took a 10% shareholding threshold, an initial dismissal in 2025 over a proxy-form dispute, and nearly 18 months of litigation. In 2025, Lant claimed backing from 12% of more than 850,000 shares held by about 6,500 owners, and reformers floated lowering the threshold to 5% and letting the court initiate investigations itself. Neither has happened.

Compare that with mainstream corporate law. In 2026, BusinessDesk’s analysis of the Mainzeal judgment argued courts increasingly weigh “the quality of governance processes that led to those outcomes”, not just the outcomes. Academic work on NZ’s finance company collapses found the same failure patterns recurring: dominant architects, thin skills, directors underinformed or disengaged. Process is where losses are born. Mangatu’s examining officer has been told to look at the bill, not the process.

What happens next

The officer’s report should at least settle the $29.5 million dispute over the size of the loss, and that alone is worth having. But the Māori collective asset sector now manages billions in land, forestry, fisheries and commercial investments, and its owners deserve scrutiny mechanisms at least as sharp as an NZX retail shareholder gets. Lowering the trigger threshold and giving the Māori Land Court power to act on its own motion are sensible, low-cost fixes. Until Parliament makes them, the lesson for every iwi and hapū entity board is simple: document the advice, test the downside, and tell owners early. If the court won’t ask who made the call, shareholders at the next AGM will.
