$620 million deal creates an $18.3 billion NZ-owned banking challenger

The deal the government didn’t want

On 27 August 2026, Toi Foundation trustees voted to proceed with Heartland Group Holdings’ $620 million proposal to acquire TSB Bank. It is a genuinely significant moment in New Zealand banking, and it happened despite Wellington’s clear preference for a different outcome.

Finance Minister Nicola Willis had publicly backed the idea of Crown-owned Kiwibank growing by acquisition, noting it “could also grow through mergers or acquisitions” that would represent “step changes in market presence which might otherwise take years to achieve.” A Kiwibank-TSB tie-up would have created a $55 billion bank, the largest locally owned lender in the country.

But Toi Foundation was under no obligation to wait for politics to catch up. The Heartland deal had been in train since June, and the trustees judged it on its merits.

Kiwibank talked, Heartland delivered

Toi chair Chris Ussher was blunt about why Heartland won. “From the proposals we received, Heartland Group Holdings is the best deal,” he said, citing both value and “complementary strengths” around job retention, branch retention and TSB’s Taranaki presence.

The telling detail is what Ussher said next. Toi had “proactively engaged with a range of parties at the beginning of the process, but after some initial information sharing, not all chose to make an offer.” That is a pointed reference to Kiwibank. Its Crown-owned parent, Kiwi Group Capital, made an eleventh-hour public push, with chairman David McLean claiming Kiwibank had “a superior proposal ready for the trustees to consider.” Toi’s statement makes clear that superior proposal never turned into a formal offer during the actual process.

Kiwi Group Capital’s response to the vote was a face-saving line about continuing to “build a stronger New Zealand-owned banking alternative.” Translation: the door on TSB is shut.

What the money actually buys

The $620 million is not a clean cash sale, which is where the Taranaki opposition has focused. Under the Toi information booklet, the consideration includes a $264 million vendor loan back to Heartland at 6.9%, $56 million of subordinated debt, $250 million in Heartland shares giving Toi roughly 17.5% of the group, and a $50 million pre-completion dividend.

Former TSB chair Elaine Gill captured the structural oddity in June 2026, saying she was “absolutely devastated” and pointing out “we’re also giving it $250 million loan so that they can buy us.” The total represents about 76% of TSB’s book value, a 24% discount that sits at the centre of community anger. Nearly 7,000 people signed a petition to keep TSB locally owned.

For Toi, the logic is distributions. Its average annual dividend from TSB has been about $10 million; the booklet projects $34-37 million in annual yield from the Heartland instruments, rising to $50-60 million longer term. That is why the discount was tolerable.

What a bigger challenger means for business

Strip out the politics and the deal is strategically coherent. Heartland has been strong in reverse mortgages, motor vehicle and business finance but lacked a retail deposit base and home loan book. TSB supplies both. Forsyth Barr analysts Ben Crozier and Andrew Harvey-Green noted in June 2026 the merger “gives Heartland Group Holdings a solid starting point in the significant NZ home loans market that it lacked when it attempted to enter the market organically.”

The numbers behind it are healthy. Heartland reported FY2026 net profit after tax of $93.2 million, up from $38.8 million, and estimates roughly $34 million a year in cost synergies once fully realised. The combined entity would hold $18.3 billion in pro forma total assets, by far the largest NZ-owned bank outside the Australian majors.

The risks are real. Forsyth Barr flagged “meaningful execution risks” around technology integration and TSB’s return on equity of around 6%, well below Heartland’s 12% target and its cost of capital. That underperformance is precisely what justified the below-book price.

What happens next

The vote clears a major hurdle but not the last. A High Court bid to block the trustees’ vote was dismissed on 24 August 2026. Heartland shareholders still vote on 30 September 2026, and the deal needs RBNZ and Australian regulatory sign-off. CEO Andrew Dixson says the company remains “on target for a 1 December completion”.

For business borrowers weary of the big four, a genuinely larger domestic challenger with a home loan book and a business lending arm is the most interesting competitive development in years. That it arrived over the government’s stated preference, on commercial merit, is the part worth remembering.
