The bill amends the Constitution Act 1986 to permit a 4‑year maximum term of Parliament, but only if two conditions are met: a majority of voters in a specified referendum vote for the change and the Governor‑General, on the Prime Minister’s advice, issues a Proclamation after the House confirms a statutory proportionality test for select committee membership. The change does not take effect automatically; most of the Act only comes into force on the writ issue for the first general election after an official declaration that the referendum favored the 4‑year option.
Section 3 (the repeal rules) comes into force immediately.
Why it matters: the bill is a carefully conditional constitutional change rather than a simple statutory lengthening of terms. It embeds procedural safeguards—the concurrent referendum, a specific resolution deadline for Parliament, and a numerical test for committee composition—while also updating the Electoral Act’s election‑timing calculations.
For officials, parties, and compliance officers the bill creates precise administrative triggers and new counting rules that will shape election planning and parliamentary business if the referendum succeeds.
At a Glance
What It Does
The bill replaces the 3‑year term in section 17 of the Constitution Act with a mechanism allowing a 4‑year term only after (1) a majority 'yes' in a specified referendum conducted with a general election and (2) a Proclamation by the Governor‑General made on the Prime Minister’s advice following a House resolution that a statutory proportionality test for select committees is satisfied. It also amends the Electoral Act’s timing (default day) and updates reserved‑provision references.
Who It Affects
Directly affected are members of Parliament (Ministers, Parliamentary Under‑Secretaries, and non‑executive MPs), the Business Committee and Parliamentary Service (which allocate select committee memberships), the Electoral Commission (which must run the referendum wording specified in the bill), and executive government because proclamation authority lies with the Governor‑General acting on ministerial advice.
Why It Matters
This is not just a term‑length change: it conditions longer terms on a parliamentary composition safeguard and a public vote, making future amendment harder by tightening the constitutional reservation and embedding operational steps that affect election calendars, select committee makeup, and how governments manage legislative programs.

What This Bill Actually Does
The bill creates a two‑stage pathway to move New Zealand from a 3‑year maximum parliamentary term to a 4‑year maximum. First, the Act fixes the exact wording of a referendum question and requires that the referendum be held concurrently with a general election; the bill also authorises a fresh referendum if a court later declares the first void.
If a majority of voters select the option to change to a 4‑year term, the Act does not flip a switch immediately. Instead, the primary parts of the Act come into force on the day the writ is issued for the first general election held after the official declaration that the referendum returned a majority for the change.
Second, the substantive change in the Constitution Act — replacing the 3‑year rule with a 4‑year rule — is itself conditional on a Proclamation from the Governor‑General issued on the Prime Minister’s advice. The House must pass, within three months of first meeting after a general election, a resolution confirming that a statutory “proportionality requirement” for subject select committees is satisfied.
That proportionality requirement is a numerical test: calculate non‑executive seats, derive proportions held by executive and non‑executive parties, and apply those proportions to the total number of select committee memberships; the non‑executive side must hold the greater number of memberships. The bill gives an illustrative arithmetic example to show the method.The bill also addresses failure scenarios.
It repeals itself if a referendum rejects the change (with repeal effective 12 months after the referendum result is declared) or if no referendum is held concurrently with either of the next two general elections after the commencement of the repeal section (in which case repeal occurs on 31 October 2031). Once the Governor‑General issues the Proclamation and the 4‑year term begins, the bill says that the term remains 4 years even if the proportionality requirement later ceases to be satisfied.
Finally, the Electoral Act is amended so that the regulated‑period default day shifts accordingly (from 2 years 9 months after polling day for a 3‑year term to 3 years 9 months for a 4‑year term), and the list of constitutionally reserved provisions is updated to reflect the new wording.
The Five Things You Need to Know
The bill fixes the exact referendum wording and requires the referendum be held concurrently with a general election; a fresh referendum may be ordered by the High Court if a petition declares the first void.
The House must, within 3 months of first meeting after a general election, pass a resolution confirming the proportionality requirement for subject select committees before a Proclamation enabling a 4‑year term may be issued.
If the referendum rejects the change, the Act self‑repeals 12 months after the referendum result is officially declared; if no concurrent referendum is held with either of the next two general elections after section 3 commences, the Act repeals on 31 October 2031.
The proportionality requirement is a formulaic test: determine non‑executive seats, compute proportions held by executive and non‑executive parties, apply those proportions to total select committee memberships, and require the non‑executive share to be numerically greater.
The Electoral Act’s ‘default day’ moves from 2 years 9 months after the previous polling day to 3 years 9 months if the term is 4 years, altering regulated‑period calculations and pre‑election timelines.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Title, commencement and automatic repeal triggers
Section 1 supplies the Act’s formal title. Section 2 stages commencement: section 3 (the repeal rules) comes into force the day after Royal assent; the substantive amendments come into force only on the day the writ is issued for the first general election held after an official declaration that a concurrent referendum returned a majority for the 4‑year option. Section 3 sets two self‑repeal paths: a rejected referendum (with a 12‑month lag) and failure to hold the required concurrent referendum within the next two general elections (fixed repeal date 31 October 2031). These mechanics force a time‑limited window for the referendum pathway to play out and give administrators clear calendaring points for implementation or lapse.
Substitutes 3‑year rule with conditional 4‑year rule and definitions
This replacement rewrites section 17: it preserves a descriptive heading for a three‑year term, then inserts a separate ‘four‑year term’ regime that only applies if a Proclamation is issued by the Governor‑General on the Prime Minister’s advice. The section tightly defines ‘executive member,’ ‘non‑executive member,’ ‘party,’ and ‘subject select committee’ for the purposes of the proportionality test, turning what might be a political judgment into a statutory calculation that business managers must deliver.
Three‑month resolution deadline; permanence of proclamation
The House must pass the confirming resolution not later than three months after Parliament first meets following a general election. The bill requires the Proclamation be issued ‘as soon as is reasonably practicable’ after that resolution. Critically, subsection (6) makes a Proclamation durable: once the 4‑year term is proclaimed, a subsequent failure to maintain the proportionality condition does not undo the 4‑year term. That locks in the extension once the formal prerequisites are met and the Proclamation is made.
Numerical proportionality test for select committees
The bill prescribes a three‑step arithmetic method to allocate subject select committee memberships: count non‑executive seats, compute proportions held by executive vs non‑executive parties, and apply those proportions to the total committee memberships, rounding to whole numbers. The included worked example clarifies rounding conventions and shows how the test can be satisfied in practice; but it also hands the Business Committee a binding allocation input and invites scrutiny over counting rules.
Electoral timing adjustments and constitutional reservation updates
Part 2 amends the Electoral Act to change the ‘default day’ used in calculating the regulated period prior to an election from 2 years 9 months to 3 years 9 months if the term is 4 years. Section 268’s replacement tightens the list of constitutionally reserved provisions to explicitly include the new subsection references relating to a 4‑year term and its proportionality clause, preserving higher thresholds (75% of members or a public poll) for future repeal or amendment of those parts.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Voters seeking longer parliamentary terms: a successful referendum gives electors a direct decision on term length and, if passed, extends the period between general elections, which proponents argue enables longer policy horizons.
- Non‑executive parties and backbenchers: the proportionality requirement increases the numeric share of subject select committee memberships for parties without executive roles, which strengthens oversight capacity and committee influence relative to the executive.
- Government planners and major infrastructure projects: a 4‑year term, once secured, affords governments a longer, more predictable policy and delivery window for multi‑year programmes and capital projects.
Who Bears the Cost
- Cabinet and governing parties: the proportionality test shifts committee memberships toward non‑executive parties, reducing direct executive influence in select committee business and scrutiny planning.
- Parliamentary Service and the Business Committee: they must implement a statutory counting and allocation method, adjust committee sizes or memberships, and document rounding and allocation decisions—an administrative and political burden.
- Electoral Commission and public funds: the Commission must administer the specified referendum wording concurrently with a general election and may face additional costs if the High Court orders a fresh referendum following litigation.
Key Issues
The Core Tension
The bill balances two legitimate objectives—longer, more stable parliamentary terms vs preserving democratic accountability and parliamentary oversight—but does so by combining a popular vote with a technical parliamentary safeguard and an executive proclamation; that mix increases political legitimacy while concentrating decisive authority in procedural calculations and executive timing, creating a trade‑off between stability and concentrated procedural control.
The bill tries to thread competing aims—public legitimacy (a referendum), parliamentary safeguard (committee proportionality), and executive control (Proclamation on PM advice)—but leaves several operational questions open. The proportionality test converts a political allocation into a rigid arithmetic exercise; that raises immediate implementation questions around rounding, ties, vacancy handling, and whether membership counts should include temporary appointments or acting Ministers.
Business Committee practice will matter enormously, but the bill gives it only a mechanical input rather than prescribing dispute‑resolution procedures if parties contest the calculation.
Timing creates another tension. The three‑month window for the House resolution comes soon after Parliament first meets, a period often consumed by formation talks and administrative setup; contested negotiations over committee sizes could push the deadline or invite strategic manoeuvring.
The bill also makes the Proclamation irrevocable for the life of the extended term, which secures certainty but allows a narrow post‑Proclamation path for parties to game committee composition ahead of proclamation to satisfy the test. Finally, the rerouting of electoral timing and the reserved‑provision protections raise long‑term constitutional payoffs: a simple majority referendum and a Proclamation threshold enable change, but the subsequent 75% or public‑poll barrier to repealing the reserved provisions makes reverse reform politically and procedurally costly.
