“Structural trends such as increased remote working and online shopping, which were accelerated by the pandemic, have caused a rise in vacancies for office and retail properties,” the RBNZ said.
“In addition, high interest rates mean debt servicing costs have increased and property valuations have declined.”
The RBNZ identified the ongoing slowing in the New Zealand economy as the “key near-term risk” facing the commercial property sector.
It also said the removal of depreciation deductibility “could add to existing cashflow pressures”.
The portion of non-performing bank loans secured against commercial property jumped to 1.1 per cent in March, from 0.3 per cent in March last year.
This portion was above the 0.8 per cent non-performing loan ratio for businesses more generally.
While vacant office and retail spaces are visible to the public, commercial property only makes up 8 per cent of New Zealand bank lending.
The RBNZ noted banks in the likes of the United States are more exposed to the sector, which is grappling with similar issues to those faced in New Zealand.
Prime office vacancy rates are higher in Australian cities, however, Auckland’s secondary office vacancy rate is high relative to that across the ditch.
The RBNZ noted migration has seen New Zealand’s population grow faster than new commercial property has been developed. This has enabled commercial property owners to put rents up.
While this is a positive for building owners, it’s a negative for tenants, who Inland Revenue fears will also end up paying for the higher tax bill owners will face in the absence of being able to deduct deprecation as an expense.
Inland Revenue warned the Government against making this tax change, which will hurt businesses and hamper productivity.
The RBNZ noted banks are usually willing to support stressed customers but said some property owners may look to reduce the size of their portfolios.
The issue is the market has been quiet since 2021, which could make deleveraging hard.
“A global commercial property slowdown could further exacerbate this as it could weaken foreign investors’ appetite for property in New Zealand,” the RBNZ said.
“This would further reduce the pool of potential buyers.”
