Solid bar: documented match. Hatched bar: unscored weight. Unscored topics earn no confirmed points; they are not opposition. Close scores do not establish a meaningful order.
Read the pattern, not the decimal. National and Opportunity are effectively a leading pair on these tests. Labour, the Greens and ACT form a second cluster. Their strengths—and their conflicts with our plan—are different.
We require evidence covering at least 70% of the selected topic weights for an overall rank. This is a minimum research threshold, not a quality rating.
Room for agreement
Start with the work we could share.
These are our proposed areas for discussion. No party has agreed to them.
01 / Build and maintain
A lasting housing deal.
National, ACT and Opportunity share substantial elements of a supply-led approach. The Greens and Te Pāti Māori also support more housing. Zoning, infrastructure funding and procurement offer practical negotiating ground.
National, Opportunity and NZ First all propose compulsory KiwiSaver with higher contributions. The next discussion is the rate, transition, household affordability and how it fits with Super.
Labour’s GP-practice and data-centre proposals create concrete overlap. National and the Greens also have health-capacity policies. A useful agreement could specify additional capacity, who pays and how success is measured.
These are interpretations of the linked policies below, not forecasts of coalition willingness.
Side by side
Where we meet. Where we differ.
National
Close on supply, investment, saving and teaching; rejects the tax switch.
59/100100% of topic weight assessed0 points unresolved
Common ground
Housing and infrastructure supply, renewable and backup generation, compulsory KiwiSaver, structured literacy and healthcare capacity.
Different approach
No new taxes rules out our CGT-funded switch. Housing density rules, Super timing and the conditions on large power loads also differ.
A possible agreement
Preserve useful housing reforms and structured teaching; agree on infrastructure funding, retirement saving and transparent service outcomes.

Next New Zealand
A broad realised capital gains tax, excluding the family home and KiwiSaver. Certified receipts fund a company-tax cut to 25% and wage-indexed income-tax thresholds. Keep Investment Boost and easier overseas investment.
Three storeys as of right in the six largest cities; six near rapid transit. A $2bn infrastructure bank lends against targeted rates. Maintain assets, publish project costs and preserve useful planning reform.
Remove entry barriers, strengthen open banking and allow divestiture after demonstrated harm and a net-benefit test. Test gentailer separation before using it. Grow Kiwibank with private capital.
Faster renewable consenting, firm backup including an LNG bridge, and repayable solar finance. Loads above 50MW must bring firmed supply or equivalent flexibility and pay their network and water costs.
Compulsory KiwiSaver: 5% employee plus 5% employer within three years of our first 2030 Budget. Protect over-55s; raise Super’s age from 2036 to 67 in 2047, then link to longevity.
Build capacity and retain clinicians, with targeted loan relief trials and nurse practitioners. Start appointments within seven days in 40 underserved areas, with published access measures.
Keep structured literacy, maths and explicit teaching. Fund small-group tutoring for 40,000 pupils and teacher coaching. Stabilise qualifications and reward apprenticeship completion.
Stage permanent commitments behind identified funding and certified receipts. Count no assumed efficiency or growth dividend. Separate operating and capital costs; publish outcomes and unresolved costs.
Keep net zero and a credible ETS cap. Start agricultural measurement and technology trials, with a 2030 pricing backstop if needed. Publish adaptation responsibilities and cost sharing.
The January 2026 programme presented by National minister Simon Watts retains net zero and emissions budgets, but removes on-farm pricing by 2030.
Why this score
Net zero and technology investment overlap. Removing the 2030 pricing commitment differs from our pre-announced backstop if verified progress falls short. This scores the current governing programme, not an old party webpage.
A three-year population and capacity plan covering all flows, with health and construction pathways, portable worker visas and enforcement against exploitation. No arbitrary net-migration quota.

What we are measuring
Similarity to the economic prescriptions on this site, across the six moves plus retirement, fiscal discipline, climate and migration. This is our editorial assessment, not independent economic modelling, a voting recommendation or a prediction of delivery.
The six parliamentary parties and Opportunity are included. Smaller parties are outside this first review. Treaty and constitutional arrangements, defence, justice, pay equity, childcare and other commitments need separate comparisons; they are not quietly folded into an economic score.
How the numbers work
For each topic: weight × score ÷ 4. Add the points. The default weights prioritise tax and housing, then competition and energy. “Every topic equally” gives each 10%. They are stated editorial priorities, not estimated GDP effects.
Unknown topics contribute no documented points and remain visibly unresolved. A party’s possible total runs from its documented points to those points plus the unresolved weight. This is an evidence range, not a statistical confidence interval. We do not rank parties with less than 70% coverage.
What earns a score
4: Close match on the major mechanisms and safeguards.
3: Substantial shared mechanisms; material details differ.
2: Some shared mechanisms, with substantial differences.
1: A shared objective or narrow element; the main approach differs.
0: Explicit opposition to the central policy direction.
?: Insufficient verified current evidence.
How to read the evidence
Snapshot checked on 10 September 2026. Party policy pages and dated announcements take priority. Current governing programmes are identified as such; coalition membership alone earns no credit. Where primary detail was unavailable, the September retirement comparison from Local Matters is explicitly linked. An announcement is not proof that its funding or results will materialise.
Evidence coverage means we can make a judgement on a topic; it does not mean every sub-policy has been announced. Near scores are effectively a cluster. Weight changes and new announcements can change the order.
Hold our plan to the same standard.
Our tax receipts, delivery capacity and commercialisation strategy also need testing. Read the commitments register and stated gaps alongside this comparison.
