Rents: a $180 rise versus “flat” under National
A $180 rise can be reproduced using selected new-tenancy medians, and the latest annual all-tenancy rent index is flat. But that index rose about 5% from the first full month of National’s term to August 2026. The post leaves the different measures and periods unstated.
What was claimed
Exact wording · Simeon Brown / National Party
Under Labour, average rents increased by $180 a week. Under National, rents are flat.
Claim made . This check uses National’s dated 13 October release, matched to the supplied Facebook screenshots. The original Facebook permalink was not recovered.
Context and implied message
Our interpretation: The rent comparison is used to blame Labour for the increase and credit National with flat rents. It suggests both a whole-term comparison and policy responsibility.
What the evidence establishes: The $180 matches selected new-bond median endpoints, not an average across all tenancies. Recent annual flatness is not flat rents over National’s whole term: the stock index is about 5% above December 2023. None of these endpoints isolates government effects from supply, demand or other influences. Misleading is retained for the measurement, period and attribution problems.

Why this rating
MBIE’s national median for new private rental bonds was $400 in October 2017 and $580 in October 2023: a $180 weekly rise. National’s own September 2023 explanation explicitly referred to a median. A median of new bonds is not the arithmetic mean rent paid by all existing tenants, and changes in the mix of properties can affect it. Brown’s post does not name its source months.
There is genuine evidence of recent flat rents. Stats NZ’s August 2026 stock rental index recorded 0.0% annual growth, rounded to one decimal; its flow index recorded 0.9%. In the MBIE series, July 2025 and July 2026 also both had a $590 new-bond median. These support a clearly defined recent comparison.
That is different from saying rents did not increase across the National-led government’s term. Stats NZ’s stock index rose from 1,723 in December 2023, the first full month after the government change, to 1,810 in August 2026: about 5.0%. Using the November transition month gives about 5.5%. These are changes in an index, not weekly dollar changes.
The new-bond median gives a different term comparison: $585 in November 2023 and $590 in July 2026, only $5 higher. The conclusion is therefore sensitive to the measure and dates. The rating concerns the post’s broad comparison without these definitions; it does not deny the $180 median calculation or the latest flat annual stock reading.
The surrounding release uses the rent comparison to blame Labour and credit National with a turnaround. The rent series records market outcomes, not a controlled estimate of government effects. Supply, demand, tenancy composition and other influences matter; this review does not assign either government zero influence or all responsibility.
The numbers and definitions
Reproducing the $180 figure
- Claim stated
- $180 more per week
- Evidence
- $580 − $400 = $180. These are national new-bond medians.
- Period / measure
- October 2017–October 2023
A recent flat measure
- Claim stated
- Rents are flat
- Evidence
- Stock index: 0.0% annual growth; flow index: +0.9%.
- Period / measure
- August 2026 versus August 2025
Same stock index over a longer period
- Claim stated
- Rents are flat under National
- Evidence
- (1,810 ÷ 1,723 − 1) × 100 = 5.0%. Using November’s 1,715 gives 5.5%.
- Period / measure
- December 2023–August 2026; November is the transition month
New-bond median over the term
- Claim stated
- No measure or start month specified
- Evidence
- $590 − $585 = $5. Using October 2023’s $580 instead gives $10.
- Period / measure
- November 2023–July 2026; provisional MBIE data

Missing context and limits
- National took office on 27 November 2023. A monthly series cannot align exactly with that day; both the transition-month and first-full-month index comparisons are shown. October 2023 is an election-month proxy, not the exact end of Labour’s administration.
- Tenancy Services warns that the current bond-data migration leaves its series provisional and recent values may be revised or not directly comparable. Small median or geometric-mean movements should not be treated as precise policy effects.
- The $180 calculation reproduces a possible median comparison. Brown’s precise endpoint selection remains unstated. No rent series by itself proves that a political party caused the change.
Primary sources and verification
AI-assisted review: the dated claim, both agencies’ definitions and current release were read. National ALL rows were extracted from the MBIE CSV, and Stats NZ national stock/flow observations were extracted from its CSV. Dollar differences and percentage changes were independently recomputed. Migration and endpoint limits remain explicit. No external human editorial review is recorded.

How we fact-check
We select specific, testable assertions from attributable statements and reader submissions. National and Labour face the same criteria. This is selected coverage, not a party scorecard or a claim that every campaign statement has been checked.
Evidence and ratings
We prioritise original statistics, legislation, agency documents and parliamentary records. A party’s statement establishes what it said; it is not independent proof against another party. For claims about a published plan, a reproduced calculation establishes its arithmetic, not whether its forecasts will happen.
Context matters
Checks identify the period, publication date and definition of each measure. We distinguish headcount from full-time equivalents, price levels from inflation, adjusted from unadjusted statistics, and forecasts from results.
Blame, credit and the full message
We read the surrounding words and images, including implied claims that a party caused a problem or deserves credit for an improvement. A correct number does not by itself prove that attribution. We label our interpretation, show the source context and explain what the evidence can establish. The same test applies to criticism by either party and to claims about its own achievements.
An attack is a reason to examine responsibility, not automatic proof of a falsehood or an unsupported motive. A recorded vote or directly implemented policy can support a specific claim. For wider outcomes, we look for evidence of the proposed causal link and consider other influences. Missing evidence does not prove a policy had no effect. Where accurate figures create a materially unsupported impression of blame or credit, the full message can be Misleading; where a conclusion cannot be established, we use Unverified. Future consequences remain predictions.
Each entry states its scope. “Full message assessed” includes the selected claim’s material factual implications, not every other assertion in the source. “Factual component checked” limits the rating to a documented action or assertion and explains broader implications separately. Promises, predictions and opinions receive context without an accuracy verdict.
Future promises, predictions and opinions
These entries explain what was proposed or argued. A future promise is a commitment whose delivery remains to be assessed; a prediction describes possible outcomes; an opinion expresses a judgement. We provide sources and context without assigning an accuracy verdict. Any testable factual assertions within these statements can be checked separately. A factual claim with insufficient evidence is labelled Unverified.
AI-assisted research and independence
The initial reports use AI-assisted research and calculations. Each report explains the sources read and the limits of its verification. External human editorial review has not been recorded for this initial batch. Sponsorship and newsletter distribution cannot change a verdict or replace the evidence requirements.
Corrections and incomplete information
Unresolved assertions remain Unverified or private drafts. A changed public conclusion retains the earlier rating, explanation and dated revision reason in its correction history. Readers can submit evidence, report an error or appeal a rating using the form below. Submissions require review before publication.
Checks describe the evidence available on their verification date. New statistics or a later policy announcement may change the answer; a later document does not establish what was true on an unknown earlier posting date.
