Fewer rentals, more renters: NZ's supply gap is growing

Supply is tightening and the Canterbury warning sign is flashing

New listings in New Zealand's rental market fell 11% year-on-year in May while rental searches climbed 12% — a widening gap that points to a tighter market before the year is out.

The national median weekly rent held at $620, down just 0.8% both year-on-year and month-on-month, according to Trade Me Property's latest Rental Price Index — a meaningful shift from the steeper falls of between 1.6% and 4% recorded over the preceding 12 months.

The supply squeeze is already biting in some regions

Of the 15 regions Trade Me Property monitors, 13 recorded listing declines in May. Wellington was down 21%, Southland 16%, Bay of Plenty 14%, Otago 13%, and Canterbury 12%. Only Gisborne and Taranaki bucked the trend with notable listing increases.

Full interest deductibility returned in April — research suggests it helped soften rents, but supply is not keeping pace with rising demand.

"The supply story is the one to keep an eye on, with fewer landlords listing and more renters searching. That's a combination that historically puts upward pressure on rents," Trade Me Property spokesperson Casey Wylde (pictured) said.

If listing volumes continue falling into the second half of 2026, Wylde warned, the modest price increases Canterbury is already experiencing could spread to other regions.

Canterbury leads, Wellington lags

Canterbury is the clear national outlier, with rents up 1.8% year-on-year to $580 per week and Christchurch's unit market hitting a record $485 per week — an 8% annual increase of roughly $40 extra per week.

Wylde pointed to constrained supply as the driving force: "Christchurch continues to outperform the market. Rental demand there has remained strong, and the supply of units in particular hasn't kept pace which is pushing prices to levels we haven't seen before. If you're a renter in Ōtautahi right now, it's a tight market."

Wellington sits at the opposite end, recording the steepest decline of any major centre — down 3.2% year-on-year to $600 per week. Large 5+ bedroom properties in the capital have fallen more than 8% annually to $895 per week, pointing to a current oversupply of larger homes.

Auckland's median rent of $660 per week is unchanged year-on-year, though improved affordability appears to be attracting a broader pool of renters, with search activity up 16% year-on-year.
