Income tax overhaul: $30k tax-free, 15% to $60k, 33% to $90k, 39% to $180k, 42% to $300k, 48% above
+$55.6b
Tax: income, GST & excisePartymedium

Party estimate. Our cross-check: static microsimulation on IRD 2025 taxable-income distribution gives $13.9bn at 2025 incomes and ~$13.8bn in 2027/28 - matches. Cuts to $60k cost ~$18.3bn; higher rates (33/39/42/48) recoup ~$4.4bn statically - a behavioural response at 42%/48% (income shifting to 28-33% companies/39% trusts) would raise the true cost, plausibly to $15bn+. Confidence raised to medium. PERIOD: party gives one "estimated fiscal impact" with no year. Treated as ANNUAL (four-year = 4x, no growth). Evidence: (a) party says 4.2m people gain ~$4,000 a year = ~$16.8bn/yr, matching the $13.9bn income tax + $2.8bn kai credit costs; (b) our IRD-based microsimulation puts the income tax change at ~$13.9bn a year; (c) PREFU gross company tax ($22.1bn in 2027/28) implies ~$3.95bn a year from 28->33%, close to the $3.4bn shown; (d) kai credit $800-1,000 x ~3m people a year. Alternative reading (figures are four-year totals) would divide every four-year figure by 4; it is implausible for (a)-(c).

−$35.2b
Tax: wealth, capital & businessPartylow

Party estimate, no published method or review. Our arithmetic from party stats (3% of people, avg net wealth $6m): ~126k adults x ~$4m above threshold x ~1.7% avg rate = ~$8.6bn gross, so $8.8bn appears to assume NO avoidance/emigration loss; applying the Greens' 28.5% leakage assumption would give ~$6.3bn/yr. Party claimed $23bn from its 2023 wealth tax. PERIOD: party gives one "estimated fiscal impact" with no year. Treated as ANNUAL (four-year = 4x, no growth). Evidence: (a) party says 4.2m people gain ~$4,000 a year = ~$16.8bn/yr, matching the $13.9bn income tax + $2.8bn kai credit costs; (b) our IRD-based microsimulation puts the income tax change at ~$13.9bn a year; (c) PREFU gross company tax ($22.1bn in 2027/28) implies ~$3.95bn a year from 28->33%, close to the $3.4bn shown; (d) kai credit $800-1,000 x ~3m people a year.

Party costing. Our cross-check (Treasury ready reckoner not accessible - Cloudflare): static microsimulation on IRD taxable-income distribution 2025 (4.75m people, $278bn income; reproduces IRD tax on taxable income $61.7bn vs $62.1bn actual) gives a static cost of $1.7bn at 2025 incomes and ~$1.1bn in 2027/28 after wage growth (the fixed $160k threshold claws back more over time). Party figure is ~$1.2bn/yr higher, consistent with assuming a behavioural loss on the 45% rate (e.g. income shifted to companies/trusts; static 45% recoup ~$1.7bn). Ignores tax credits (IETC).

Repeal Investment Boost
−$7.70b
Tax: wealth, capital & businessPartymedium

Using $7.7b, the figure in Labour's 4 Oct fiscal plan. Reconciliation: the $6.6b was the gross cost of Investment Boost over the Budget 2025 forecast window (Budget 2025 documents; interest.co.nz), about $1.7b/yr, partly offset by an estimated $2.6b of growth-driven revenue. The $7.7b is the static revenue gain from repeal over Labour's window, with claims allowed to 30 June 2027 and existing assets grandparented. Four years at about $1.7b/yr, growing with the investment base, gives roughly $7-8b, consistent with $7.7b. $7.7b is therefore the right figure for this window. It is static: lost growth-driven revenue (Treasury: up to 0.5% GDP over 5 years) would reduce the net gain. Hall Chadwick reviewed the plan. Stays medium because no Treasury costing on this window was found. Annual = 4-yr / 4.

PSA (2 Jul 2026) says the real figure is $4.5b of unfunded extra employer costs for public agencies and funded providers, because the provision only covers workers not already in KiwiSaver. Per National, most agencies would absorb the rest within baselines (as in Budget 2026). Over-65 employer contributions (from 1 Jul 2027) also absorbed in baselines, no cost shown. Annual = 2030/31.

Health funding: PREFU cost-pressure track and other health (residual)
$0m
HealthOur estimatelow

Labour states $15.5b additional health funding over the forecast period combining the PREFU cost-pressure track with its announced health commitments. Residual = 15,500 minus the Medicard (2,052), free prescriptions (298) and graduate nurse (525) rows. Mostly matches spending the current Government also pencils in from its allowances, so not incremental vs the status quo. National says year-4 (2030/31) cost pressures are $1.5b unfunded. Annual = 4-yr / 4. In-baseline estimate (method): PREFU 2026 sets out coalition health cost-pressure increases of $1.4b-$1.55b per Budget for Budgets 2027-2029, none in 2030/31 (NZ Herald/RNZ, https://www.nzherald.co.nz/nz/politics/labours-fiscal-plan-answers-some-questions-but-leaves-10b-hanging/premium/RJATN744F5CNJOYC4WAVPQ6PJU/). Each increase recurs, so the cumulative 2027/28-2030/31 cost is 4+3+2 = 9 Budget-years x $1.40b-$1.55b = $12.6b-$14.0b. That is at or above this residual, so the whole $12,625m is treated as in-baseline. The low end ($12.6b) reconciles exactly with $15.5b minus Labour's announced health items, which suggests Labour adopted the PREFU track at about $1.4b per Budget. Low confidence: the per-Budget phasing was not published. Re-verified: no published figure for the PREFU cost-pressure total exists, so this stays our_estimate. Years: the PREFU track starts with Budget 2027 (2027/28).

Critics warn it could push up prices at the capped end of the market. in_baseline = full $20m because it is funded by reprioritising money already in the PREFU baselines. interest.co.nz (6 Sep 2026, citing the National policy doc): the $4-6m covers admin and support for an expected doubling of the scheme; current admin is about $14.5m/yr for about 3,085 underwritings (2024/25). Budget 2025 lowered the ongoing cost by making borrowers pay Lenders Mortgage Insurance. Confidence stays medium because only a range is given.
