Tax
Summary
The ad's sole substantive claim is "$18 billion of unfunded Labour promises." There is a real basis for the figure: National published a costing document estimating Labour had announced about $21.0 billion of spending commitments over 2027/28 to 2030/31, against $2.8 billion of forecast capital-gains-tax revenue, producing an estimated $18.2 billion gap. However, the $18.2 billion figure is National's own analysis, depends on assumptions about several Labour policies, and has not been independently established as an actual fiscal shortfall. ([National Party][1])
National has calculated an $18.2 billion gap between its estimate of Labour's announced spending and identified revenue, but the figure is National's own modelling and includes important assumptions. It should not be treated as an independently confirmed $18 billion hole in Labour's finances.

What the ad gets right
- +National has published a detailed document calculating an $18.2 billion difference between what it estimates as $21.03 billion of Labour spending commitments and $2.8 billion of announced capital-gains-tax revenue over four fiscal years. ([National Assets][2])
- +Several spending commitments included in National's calculation are based on genuine Labour announcements, including three free GP visits, free cervical screening, capped public-transport fares and commitments relating to pay equity. ([National Party][1])
- +At the time National first published the calculation, Labour had not released a complete alternative Budget showing how all of its election commitments would fit together fiscally. ([1 News][3])
What the ad gets wrong or leaves out
- −The ad presents "$18 billion" as an established fact without saying that it is a National Party estimate. Independent reporting describes it as a gap National "alleges" or "calculates," and Labour disputes the analysis. ([1 News][3])
- −Some of the largest items depend on assumptions rather than fully specified Labour costings. For example, National assigns about $2.8 billion to lost Future Fund dividends by assuming specific Crown companies would be transferred into the fund, while acknowledging Labour had not specified which companies would be included. ([National Assets][2])
- −Nearly $11 billion of the calculation comes from National's assumption about restoring the former pay-equity regime, making that single modelling choice responsible for more than half of the claimed total. ([National Assets][2])
- −Calling the entire amount "unfunded" assumes announced capital-gains-tax revenue is the only money potentially available. A future government can also fund priorities through Budget allowances, spending reprioritisation, policy offsets, additional revenue measures or borrowing.
- −Since National produced its June calculation, Labour has announced further policy details, including a small-business package funded by replacing or reducing the current Investment Boost scheme, illustrating why the funding position can change as the campaign develops. ([National Party][4])
- −The graphic gives no source, timeframe, policy list or explanation of how the $18 billion figure was calculated, presenting a contested partisan costing as an uncomplicated numerical fact.
Detailed Verdict
National can substantiate how it arrived at approximately $18.2 billion, so the number is not invented. But describing it simply as "$18 billion of unfunded Labour promises" conceals that it is a partisan estimate containing significant assumptions rather than an independently verified fiscal hole.
