National won in 2023 despite doubts over its costings

National won the 2023 election despite economists Michael Reddell and Sam Warburton finding its costings — its budget sums — “aren’t credible”, Reddell told RNZ. Leader Christopher Luxon had called the figures “absolutely rock solid”. After forming government with ACT and New Zealand First, National rewrote its fiscal plan and dropped its 15 percent tax on house sales to foreigners.
