The notice went out on September 18. The buyer told the market about it on September 25. Shareholders vote on September 30. The report that all of it turns on arrives in November.
That ordering is the story. A takeover vote is normally the moment a deal is settled or rejected, and next week's meeting in Auckland will be reported that way whatever happens. But the document that decides whether Heartland Group ends up owning TSB is being written by an accounting firm on a schedule that runs past the vote, and the merger agreement already contains the clause that lets the buyer walk if the answer comes back wrong.
What a Section 95 notice does
The Reserve Bank of New Zealand issued the notice to TSB Bank Limited under Section 95 of the Banking (Prudential Supervision) Act 1989. The provision lets the supervisor require a bank to commission independent assurance about its compliance with prudential requirements. In this case the requirements named are liquidity, capital adequacy and regulatory reporting.
The power is not a penalty and does not assert that a bank has broken a rule. What it does is remove the supervisor's reliance on the bank's own account of itself. Prudential supervision runs on reported numbers: a bank calculates its capital ratio, files it, and the supervisor monitors the ratio against minimums, uses it to set intensity of oversight, and in a stress episode uses it to decide how much room the bank has. If the calculation itself is the question, then every downstream judgment rests on an answer nobody has verified. Ordering an outside firm to check the arithmetic is the supervisor's way of converting an internal concern into a documented finding it can act on.
Such notices are uncommon in New Zealand. RNZ reported that only a handful have been issued in recent years, which is part of why the disclosure matters beyond TSB. A supervisor that rarely reaches for this tool is signalling that the usual escalation steps, engagement and formal warnings among them, were not enough or not appropriate.
TSB reported its own numbers as unreliable
The bank identified issues concerning aspects of the computation and reporting of its capital and liquidity ratios and told the regulator, according to the disclosures published this week. Deloitte New Zealand will act as the independent reviewer, and the Reserve Bank expects a final report in November 2026.
The scope is narrow in a way that makes it broad in effect. Capital adequacy and liquidity are not side calculations in a bank. They are the two measures that determine how much lending a bank can support, how much it can return to its owner, and how it is treated in a crisis. A ratio that has to be recomputed can move in either direction once the work is done, and the recomputation touches every period the affected figures were reported in.
For a bank operating on its own, that is a supervisory problem with a timetable. For a bank in the middle of being sold, it is a pricing problem, because the buyer agreed to a number that was derived from the figures now under review.
The dates that now matter
Heartland's special shareholder meeting will go ahead as planned on Wednesday, September 30, held online and in person at Eden Park, with the board unanimously supporting each resolution. Shareholders who have already voted may change their minds until 3 p.m. on Monday, September 28.
The shareholder documents, including the notice of meeting, the investor presentation and the independent expert report, were published on August 31, before TSB received the notice. That gap is the crux of the disclosure Heartland made on Friday, and the company said so in plain terms: because the transaction remains subject to its remaining conditions, if the outcomes of the review are materially different from what is known today, the deal may not complete even if shareholders approve it.
Heartland's chief executive, Andrew Dixson, said the company would weigh any findings as they arrive, including any implications for the transaction, and repeated the strategic case for combining Heartland Bank's specialist lending with TSB's everyday banking business. He also said the transaction still carries several conditions, which he described as an important protection for shareholders. Heartland and Toi Foundation, TSB's owner and the seller in the deal, are engaging with the Reserve Bank about the proposal.
The clause that carries the weight
A material adverse change condition is the part of a merger agreement that lets a buyer withdraw when something breaks in the business between signing and completion. It is normally drafted for the catastrophes everybody imagines: a collapse in earnings, a regulatory shutdown, a market that stops functioning. It is deliberately hard to trigger, because a seller will not sign a deal that a buyer can abandon at will.
The condition in this transaction now has a live question to answer. Heartland said that its due diligence before signing the merger implementation agreement identified matters that were reflected in the commercial and contractual terms, and that the investor presentation it gave shareholders in August listed forecast risks, regulatory risks and the risk that the deal does not complete if conditions are not met. What the August documents could not do was describe a notice that had not been issued yet. The notice came four days later.
The clause also distributes leverage unevenly. A buyer that invokes it can stop; a seller cannot compel completion. That imbalance is normal, and it is why sellers spend their negotiation on the thresholds and exceptions inside the definition rather than on whether the condition exists at all. What is unusual in this case is the source of the uncertainty. These conditions are usually drafted against shocks from outside the business, which is why the standard carve-outs cover general economic conditions and changes in law that hit everyone the same way. A supervisory demand to verify the seller's own regulatory reporting is a different kind of event. It is a question about the accuracy of the thing being sold, which is closer to what such a condition exists for than anything a market-wide crisis would produce.
This is where the accounting question becomes a legal one. If Deloitte's report confirms what TSB has already told the regulator, the parties can treat it as an expected correction, adjust whatever needs adjusting, and proceed. If the report finds the position materially different from the understanding the deal was priced on, then the buyer has a documented path to walk away, and the seller has a dispute about whether the threshold is met. Either way, the decision does not belong to the meeting on Wednesday.
Why capital calculations are the hard thing to diligence
A capital ratio looks like a simple fraction. It is not. The numerator depends on which instruments count as capital and how deductions are applied, and the denominator depends on how assets are weighted, which turns on the risk assigned to each exposure, the treatment of expected credit losses, and the way deferred tax assets are netted. Two banks with identical loan books can report different ratios because of choices inside those rules, all of them permitted and all of them disclosed somewhere in the notes.
A buyer's diligence tests the numbers it is given. It re-performs the arithmetic, compares the assumptions with peers, and checks that the accounting matches the transactions underneath. What it usually cannot do is establish that the bank computed its ratio correctly in the first place, because that requires the bank's own model, its data lineage and time. That is the gap an independent assurance engagement fills, and it is why the Reserve Bank asked for one rather than accepting a restatement.
The commercial consequence is that the number at the centre of the deal is now being produced by a process the buyer does not control, on a timeline the buyer does not set, with a result that can invalidate the price without anyone behaving badly. TSB has not been accused of misconduct. It reported a problem with its own reporting, which is the outcome a supervisor builds these channels to produce.
What happens between now and November
Shareholders who vote against the transaction have minority buy-out rights they can exercise, and the deadline for changing a vote falls two days before the meeting. The remaining conditions include the shareholder approval itself, the material adverse change condition, and the regulatory approvals the transaction requires. A completed vote on Wednesday moves the deal to the regulatory stage, where the same supervisor that issued the Section 95 notice will be weighing the results of a review it commissioned.
The likelier outcome is still that the review confirms the figures as substantially correct, or produces a correction the parties absorb and move past. Banks restate ratios, adjust for the change and complete transactions, and the fact that TSB reported the problem itself is the outcome a supervisory regime is designed to produce rather than a sign of something worse behind it. What the process has already changed is the information position of everyone involved, and that change does not reverse. Heartland and the seller have seen the files. Shareholders are being asked on Wednesday to approve a price set from those files without seeing the verification. The only participant that will hold a checked version of the numbers before completion is the regulator that ordered the check.
Heartland has said it will not speculate about the outcome before the findings are available. That is the only position available to it, and its restraint is also a signal about how the company reads the risk. A buyer confident that a review will confirm its own diligence does not need to tell the market that the deal might not complete.
The vote next week will produce a headline and a number, and the coverage will treat it as the decision. It is better understood as a step. The owner of TSB reported that its own capital arithmetic needed an outside check, the buyer priced the bank before that check was requested, and the paperwork allows the buyer to leave if the check goes the other way. Whatever shareholders decide on Wednesday, a firm they did not hire will tell them in November what they were voting on.
