Key Takeaways
- Christchurch (and likely Auckland) is experiencing a surge of half‑finished, two‑bedroom townhouse developments that are not selling.
- In March, 79 % of all building consents issued in Christchurch were for multi‑unit projects, yet many units—especially those lacking a garage—remain unsold.
- Builders who entered the market during the 2021‑2022 price boom now face overbuilding, with some projects stalled and placed under mortgagee action.
- Two‑bedroom townhouses without parking have seen dramatically low demand; only 56 of 512 units inspected from January‑March had a garage.
- Buyers are shifting back toward traditional, stand‑alone three‑bedroom homes, causing price depreciation for units purchased in the peak years (≈ $100,000 loss on resale in 2025‑2026).
- The lag between consent approval and actual construction exacerbates the mismatch between supply and current market appetite.
Builder’s Perspective on the Christchurch Market
Carl Taylor, a seasoned builder and head of the Combined Building Supplies Co‑operative, told RNZ’s Nine to Noon that Christchurch is witnessing a growing number of half‑finished two‑bedroom developments. He noted that the trend is not isolated to the South Island; similar patterns are likely emerging in Auckland. Taylor’s firsthand experience—seeing unsold units while driving around town—has led him to conclude that the market is entering a vicious cycle of overbuilding and weak demand.
High Share of Multi‑Unit Consents
In March alone, 79 % of all building consents issued in Christchurch were for multi‑unit developments, according to Taylor. He described the visual cue of “five units available and eight in the whole development” appearing on street signs, signalling that many approved projects are not translating into sales. This disproportionate share of consents highlights a misalignment between regulatory approvals and actual buyer interest.
Two‑Bedroom Units Struggle to Sell
Taylor emphasized that while some two‑bedroom townhouses are still moving, the majority—particularly those without a garage or dedicated carpark—are languishing on the market. He pointed out that builders assumed recent years made it easy to profit from intensifying sections, but the current oversupply has left many units sitting unsold. The lack of parking appears to be a critical deterrent for prospective purchasers.
Construction Lag Exacerbates Oversupply
There is a notable delay between when a consent is granted and when construction can actually begin, Taylor explained. In 2021‑2022, builders could quickly acquire land, erect five or so units, and capitalize on a rapid price surge. That window has now closed; the lag means that many projects approved during the boom are only now reaching completion, arriving at a market that has already cooled.
Price Surge Fuels Overbuilding
During the 2021‑2022 period, property values in Christchurch nearly doubled almost overnight, making multi‑unit developments highly attractive to builders. Taylor recalled that the sudden price jump encouraged a wave of intensification, with many developers buying land and stacking units. However, the rapid influx of similar projects has now resulted in an oversaturated market, especially for two‑bedroom layouts.
Half‑Built Developments and Mortgagee Action
As a consequence of the overbuilding, several developments have been left half‑finished after their builders went insolvent. Taylor said these stalled projects have been forced into mortgagee action, where lenders take control to recover debts. He summarized the situation bluntly: “We’re in that position where we’ve just overbuilt these things.” The visible remnants of incomplete construction serve as a physical testament to the market’s miscalculation.
Price Depreciation for Early Buyers
Homeowners who purchased townhouses in 2021‑2022 and later sold in 2025‑2026 are experiencing significant losses—Taylor estimated about $100,000 less than their original purchase price. This depreciation underscores the financial risk borne by early buyers who entered the market at its peak, only to find resale values eroded by the ensuing glut of similar units.
Renewed Demand for Traditional Homes
Contrary to the struggling unit market, there remains a robust appetite for stand‑alone, three‑bedroom homes. Taylor recounted a conversation with an agent who had welcomed 22 groups of prospective buyers over just a two‑week period for traditional houses, while units struggled to attract even single‑digit interest over three weeks. This shift suggests buyers are gravitating toward more conventional layouts that offer greater space, privacy, and parking.
Implications and Outlook
The current dynamics point to a need for builders and policymakers to recalibrate expectations. Continued reliance on two‑bedroom, garage‑less townships risks further financial strain and urban blight from abandoned sites. Encouraging developments that align with buyer preferences—such as homes with parking, private outdoor space, and flexible layouts—could help absorb excess capacity. Meanwhile, monitoring consent issuance and ensuring a tighter link between approval timing and market demand may prevent future cycles of overbuilding and half‑finished projects. The Christchurch experience serves as a cautionary tale for other New Zealand cities navigating similar intensification pressures.
