Westpac compares housing, tax, and rate policies as New Zealand votes
New Zealand mortgage advisers head into the 7 November 2026 general election with interest rates finely balanced and housing policy squarely on the ballot. Westpac economists say the outcome is close and unusually hard to call.
Rates sit at a turning point going into the vote: the Reserve Bank of New Zealand (RBNZ) held the official cash rate at 2.75% on 28 October in a 4–3 vote, with all members agreeing tighter policy is likely, subject to the outlook.
The vote also comes against a soft housing backdrop: national property values fell 1.3% in the year to September, according to Cotality, leaving the market more than 18% below its peak.
The debate over the RBNZ’s mandate
The clearest monetary policy difference between the blocs is the central bank’s mandate. National would keep the RBNZ’s sole price-stability objective, while Labour would restore the dual mandate of price stability and maximum sustainable employment.
In a pre-election bulletin, Kelly Eckhold (pictured), Westpac chief economist, said a return to the dual mandate “could mean that the RBNZ is prepared to accommodate a slower return of inflation to target to reduce the impact on employment”.
Westpac says fiscal, labour, migration, and energy policy may have the larger near-term influence, however. Spending restraint under a right-leaning government would cool demand, while a larger spending programme on the left would heat it.
Housing and tax: where the blocs differ
Westpac sees two likely outcomes. The first is a returned National-led coalition, with ACT and New Zealand First holding more sway. National has ruled out new tax cuts next term and plans to widen First Home Loan access to 5% deposits, alongside planning reform aimed at freeing up land. ACT would push for deeper spending cuts, while New Zealand First pairs a more interventionist approach with selective tax relief, such as a 20% company tax rate for small and medium enterprises (SMEs).
The second is a Labour-Green government backed by the Opportunity Party. Labour proposes a 28% capital gains tax on gains accruing after 1 July 2027 from investment residential and commercial property, with exemptions, plus 6,000 additional state houses. The Greens’ platform includes a 2% annual cap on rent rises, though Labour has ruled out supporting the Greens’ tax policies.
Why the result may take weeks to settle
Labour and National were less than a percentage point apart on Kiwipoll’s six-poll tracker, last updated on 20 October, and drew a combined 56.6%. Westpac said “the bigger story is fragmentation”.
The Opportunity Party is pivotal. Averaging 6.2% in polls, it would hold seven seats, enough to tip either bloc over the line. A result below the 5% threshold, without an electorate win, would favour the centre-right.
Official results are not due until 27 November. Whatever the outcome, government borrowing will be costly. According to Westpac, “the hurdle that must be crossed to justify raising debt is higher than it has been for years”.
