NZ Rents Through August 2026: What Bond Data Shows

Cotality’s October chart pack already said rents had stopped falling in a soft way. This note is the other side of the same story: the official bond file that sits under many yield screens. We refreshed Tenancy Services’ rental bond data against the February 2026 download that still ended in December 2025. The October publication runs through August 2026. The numbers below are from that file. They are not asking rents on Trade Me.

How should you read the territorial-authority bond file?

The monthly territorial-authority CSV is private-sector bonds only. Rows are listed by tenancy start month. Tenancy Services applies fixed random rounding and suppresses cells with fewer than five bonds. The page was last updated 13 October 2026 when we pulled it. Files omit the most recent calendar month on purpose, so an October release can still stop at August.

• Compared with: the February 2026 download of the same series, which ended December 2025.
• FindMyProperty rent screens use each territorial authority’s median in the latest month in the file.
• National ALL is the New Zealand private-bond median for that month — not a suburb median.
• Small districts can jump tens of dollars on a handful of lodgements. Do not treat those swings as a national cycle.

What did the national median do through August 2026?

For every month of 2025, the national median in the October file matches the February file: $620 in January, $600 from February to April, $595 in May–June, $590 from July to October, $595 in November, and $600 in December. The rewrite was in bond counts, not in those medians. January to August 2026 then runs $600, $590, $595, $600, $600, $595, $590, and $595. That is a flat band, not a boom.

How did the main centres move from December 2025 to August 2026?

Across 65 territorial authorities, 34 medians rose, 22 fell, and 9 were unchanged. The median change was +$2 a week. The table is the cut that matters for most investors: the main centres and a few large secondary markets.

Christchurch is the large market that actually shifted. Auckland and Tauranga did not move on the median. Wellington and Dunedin edged down $5. Hamilton is up $10. That pattern fits the October housing-market note: rents look like they have stopped falling nationally, without looking like a sharp lift.

Why do small districts swing harder?

The widest moves from December 2025 to August 2026 sit in thin samples. Mackenzie District fell from $500 to $360. Opotiki District rose from $450 to $535. Kaipara, Waimate, Hurunui, Buller, Gisborne, and Taupo also posted large dollar moves. Those rows are useful as a warning about sample size. They are a poor national signal. When a district lodges nine bonds in a month, one lease can move the median more than a whole city’s market.

What changed between the February and October file versions?

Tenancy Services says to always use the latest file. Late lodgements and processing change recent months, and history can be revised. Comparing the two downloads makes that concrete. Of 26,376 overlapping rows, 12 are identical. Active bonds differ on 26,363 of them. Median rent differs on 6,228. On territorial-authority rows, 19,565 medians are unchanged, 4,951 move by $1–$10, and 53 move by more than $50.

National active-bond totals in the October file are lower in every year. The gap is about 3% in 1993 and about 32% by 2025. Lodged bonds were also lower through 2024, then 2025 lodgements were revised slightly up as late bonds arrived. December 2025 itself: 31 of 65 territorial authorities had the median revised in the later file. Auckland stayed at $650. The national median stayed at $600. The biggest December revisions were small districts — Kaikōura −$45 on nine bonds, Mackenzie −$37, Buller +$30.

That is the honest reading for anyone modelling yield from bonds: refresh the file, expect stock counts to jump around, and judge rent levels on the latest median — not on an old download you saved in February.

What does this mean for yield screens?

FindMyProperty’s rental path uses bond-based rent against asking price. The default screen still looks for 9% gross yield on the rental strategy, as set out in how we score NZ investment properties. Meeting that bar is rare on main-centre stock. Cotality’s national gross yields are still in the high 3%s. A $40 drop in Christchurch’s bond median lowers modelled annual rent by about $2,080 before expenses. That changes which listings clear a yield filter even when asking prices have not moved.

Use the bond median as a screen. Then check what similar rentals are actually asking in that suburb. Bond data lags. New builds can skew a thin sample. Vacancy and days-to-let are not in the file. If the screen says $550 and every comparable is $480–$520, dig deeper before you bid.
