Editor’s note: This is an educational explainer about how scheme of arrangement takeovers generally work in New Zealand. It is general information, not investment advice, and does not describe any specific current event, company, or security.
Why would an acquirer choose a mechanism that requires a judge’s sign-off, when New Zealand already has a purpose-built Takeovers Code for buying listed companies? The answer lies in a single number: the approval threshold a scheme of arrangement requires is higher than a standard takeover offer, yet the process it replaces can be faster, cleaner, and more certain for everyone involved once that threshold is cleared.
Two Very Different Roads to the Same Destination
New Zealand’s default pathway for acquiring a listed company is the Takeovers Code, administered by the Takeovers Panel. Under that regime, a bidder generally makes a pro rata or full offer directly to shareholders, who each decide individually whether to accept. The bidder can end up owning anywhere from a bare majority to effectively all of the target, and compulsory acquisition of the remaining minority only becomes available once the bidder crosses a 90 percent ownership threshold.
A scheme of arrangement takes a different route entirely. Rather than a bidder buying shares from individual holders, the target company itself proposes a restructuring, most commonly a transfer of all shares to the acquirer, under Part 15 of the Companies Act 1993. This is a court-supervised process: the High Court must approve orders convening a shareholder meeting and, later, approve the scheme itself before it becomes binding. Because the mechanism sits inside company law rather than the Takeovers Code, a scheme can be used for listed companies with the Panel’s consent, and it is often chosen precisely because it can deliver 100 percent ownership of the target in one step, without the compulsory acquisition process that a Code offer would otherwise require.
The Approval Threshold That Decides Everything
The defining feature of a scheme is its voting threshold. Shareholders vote at a court-convened meeting, and the scheme must be approved by a majority in number of shareholders present and voting, representing at least 75 percent of the votes cast on the resolution. Both limbs matter: it is not enough to win 75 percent of the votes if that support comes from too small a slice of the shareholder base measured by headcount, and conversely a broad numerical majority is not sufficient if the value of votes behind it falls short of 75 percent.
This is materially higher than what a conventional takeover offer needs to succeed commercially. A Code offer can complete with the bidder holding well under 75 percent, though it will not reach full ownership or trigger compulsory acquisition without crossing 90 percent. A scheme, by contrast, is designed as an all-or-nothing proposition: clear the 75 percent value threshold and, subject to court approval, every shareholder is bound, including those who voted against it or did not vote at all. Fall short, and the scheme simply fails, with no partial outcome and no residual stake for the acquirer beyond whatever it may have already held.
Why the Court Sits in the Middle
The High Court’s involvement is not a rubber stamp, and it explains why schemes are often described as offering more certainty than they might first appear to. At the first hearing, the court reviews the terms of the meeting notice and disclosure documents before shareholders vote, checking that they fairly explain the scheme’s effect. At the second hearing, after the vote, the court examines whether the meeting was properly constituted, whether the statutory majority was genuinely achieved, and whether the scheme is fair and reasonable to those it binds, including any dissenting minority. The Takeovers Panel also typically grants an exemption allowing the scheme to proceed outside the Code, subject to conditions designed to protect shareholder interests, such as ensuring adequate disclosure and an independent adviser’s report on the offer’s merits.
This layered check, shareholder vote plus judicial review plus regulatory oversight, is what allows a scheme to bind 100 percent of shareholders from a single 75 percent vote, a power no ordinary shareholder resolution carries. It is also why boards and acquirers weigh the trade-off carefully: a scheme offers clean, complete ownership if it passes, but the higher bar, the added time for court hearings, and the need for Panel cooperation mean it is not always the faster or simpler path compared with a straightforward Code offer.
