The weakening in the data has prompted Westpac to downgrade its projections for New Zealand house price growth.
Westpac now forecasts 2.1% house price growth in 2024, down from the previous 5.8% forecast.
“Slow momentum in the housing market since the 2023 election combined with the RBNZ’s “tough love” message of keeping interest rates high for longer are the key drivers”, notes Westpac.
“The RBNZ’s stance has hardened in recent months reflecting the still uncomfortably high inflation outlook”.
“The RBNZ has indicated a longer period before lower interest rates become a realistic prospect”.
“We think this more pessimistic view has been reflected in the downturn of many economic growth and confidence indicators in recent months – the housing market included”, Westpac wrote.
However, Westpac believes that “house prices will benefit from lower interest rates in 2025 and ongoing housing shortages as construction remains weak and population growth continues”.
As a result, Westpac forecasts that prices will rise by 6% in 2025.
