Charter Schools in NZ: A High‑Cost, Low‑Accountability Experiment
Education Privatisation by Stealth Driven by ACT.

Who’s pushing charter schools and why now?
The current charter school revival is a political project led by the ACT Party, with support from National and NZ First under their coalition agreement. Associate Education Minister David Seymour (ACT) announced NZ$153 million over four years to establish up to 15 new charter schools and convert 35 state schools, arguing for “greater autonomy,” “choice,” and a focus on “student achievement.” This is not incidental; ACT explicitly frames charters as freedom from “state and union interference.”
That revival became law in late September 2024, when Parliament passed the bill reintroducing charters. Seymour publicly championed the change; RNZ recorded the political debate at the third reading, with government parties presenting charters as diversification and opposition parties calling them privatisation by stealth.
The money problem: high cost, poor value
Public data from the 2014–2018 charter trial show eye‑watering per‑student costs. Official Information Act (OIA) releases summarised by NZEI and SchoolNews found charters cost up to NZ$48,421 per student annually (≈ NZ$60,000 in today’s dollars), over six times the public‑school average (≈ NZ$9,000). Current figures for the 2025 rollout (seven schools, 215 students) equated to ≈ NZ$46,500 per student in early reporting, again far higher than system baselines.
Even supporters admit establishment years are expensive. But the opportunity cost is stark: unions and education commentators note NZ$153 million could fund hundreds of teacher aides or targeted learning support in the public system, lifting achievement without fragmenting governance.
Meanwhile, the government’s Funding Model Factsheet underscores that charter funding is largely “cashed‑up” per student, with sponsor discretion over spend. That flexibility may be attractive, but without granular public reporting, it weakens cost controls and invites inefficiency.
Accountability gaps: less transparency than public schools
Two fundamental accountability failures are baked into the model:
Transparency: The charter legislation and policy documents propose contracts and performance measures not routinely available to the public. The Chief Ombudsman warned the Select Committee that excluding charters from the Official Information Act would make them “less accountable to students, parents and taxpayers” than state schools.
Financial scrutiny: Against Ministry advice for quarterly statements, the government opted for half‑year reports with annual audits, less frequent than earlier iterations and weak for a start‑up sector spending public money. Sector reviews of the original model found confidence issues in financial oversight.
When you combine opaque contracts, looser reporting, and freedom to retain surpluses, public money moves out of the OIA’s sunlight and into private decision‑making, exactly the scenario critics mean by “privatisation by stealth.”
Labour rights and democratic overreach
The Council of Trade Unions (CTU) and teacher unions submit that charter legislation breaches ILO Convention 98 by limiting multi‑employer collective bargaining and stripping teachers of existing agreement protections if a school converts. They also warn that ministerial powers to force conversions are “undemocratic and authoritarian,” allowing direction without genuine community consent.
These risks are not theoretical; 2018 transitions exposed governance conflicts and payments that the Auditor‑General said undermined public confidence and integrity, another reminder that weak guardrails can enable poor practice.
Equity and outcomes: the evidence does not justify the hype
International research on school choice warns that uncontrolled choice tends to increase segregation by socio‑economic status unless counter‑measures are designed in (e.g., controlled choice, weighted funding). The OECD has documented this repeatedly across member nations.
Even the U.S. CREDO 2023 study, often cited by charter advocates, finds small average gains in reading/maths with wide variation by operator and strongly negative results for virtual charters. Independent reviews caution that the effects are tiny, the “days of learning” metric is methodologically contentious, and omitted variables (who chooses charters) complicate claims. In short: mixed evidence at best, policy risk at worst.
New Zealand’s own Ministry of Education briefings and the Regulatory Impact Statement (March 20, 2024) recognise that attendance and engagement are complex system issues and that structural change alone is not a silver bullet, yet ACT’s political messaging routinely treats autonomy as the cure‑all.
Policy contradiction: “freedom” rhetoric vs standardisation reality
ACT sells charters on curriculum and testing freedom. But the government simultaneously promotes tighter standardisation and clearer national performance baselines. The Ministry’s charter materials say charters need not follow the NZ Curriculum so long as contracted outcomes are met, creating misalignment with system‑wide comparability and making like‑for‑like accountability harder. Autonomy without common measures weakens public oversight, especially when the OIA is off the table.
Political ping‑pong: instability by design
New Zealand has seen this movie: charters introduced in 2014, abolished in 2018, reintroduced in 2024. Educators described the sector as political “ping‑pong” and warned that schools opened under one government may be closed or reconverted under the next. That is institutionally destabilising for students and communities and financially wasteful for taxpayers.
What robust accountability would look like (and why ACT’s model falls short)
If the coalition insists on spending NZ$153 million on charters, the minimum public‑interest conditions should include:
OIA coverage of all charter sponsors and schools (contracts, performance, finances).
Quarterly financial reporting and independent audits with public release, not just half‑year.
Admissions safeguards (controlled choice, weighted funding) to prevent segregation and protect high‑needs learners.
Common outcome measures that allow apples‑to‑apples comparison across charters and state schools.
Conflict‑of‑interest rules and related‑party disclosure are stronger than standard charity/company settings.
These are not radical; England’s academy sector publishes consolidated annual reports and accounts (SARA), with National Audit Office and Parliamentary scrutiny flagging risks. NZ should not accept lower standards for publicly funded schools simply because a party’s ideology prefers private operators.
Bottom line
Charter schools are not a cost‑effective answer to New Zealand’s education challenges. The ACT‑led revival pours public money into a model with higher per‑student costs, less transparency, weaker labour protections, and equity risks, all for mixed academic returns at best. If the coalition believes in outcomes, it should prove it with open contracts, frequent reporting, OIA coverage, and rigorous safeguards. Until then, New Zealanders have every right to view charters as a politically driven, high‑risk experiment with public funds.
