The impact beyond
the cones.

Successive roadworks around Burwood and Mairehau affect more than journey times. They also change how people reach local shops, the hospital and their neighbourhoods. This is my look at the planning history, the overlapping work, and the questions that still need answers.

Reviewed Personal research and local observations

Roadworks over time

Different projects. The same everyday journeys.

For residents, successive projects can mean repeated changes to road access, bus stops, walking routes and visits to local shops. This Gantt chart shows the sequence and overlap, including another intersection stage planned for later in 2027.

The shorter Putake repair period is easier to see at this scale. The reported September power start and November–December wastewater work are distinct from the documented bus detour. Open the 2026 chart.

Dates are based on the records and local accounts reviewed for this article. A bar locates a stage in time; it does not measure delay, count affected residents or imply that every day in a broad local period involved a closure. The traffic-light brackets show the earlier summer 2026/27 target and the locally reported second-half-of-2027 start window; neither gives a construction duration. The detailed timeline below explains the evidence. [4] [5] [6] [10] [13] [14] [17]

What the evidence shows

Public records establish a long history of intersection planning and several transport and utility projects affecting the same road network. They support a serious question about the cumulative effect on people who live, travel and do business here. They do not establish that every project could have been built together, or that every day since the first works has involved a closure.

Public recordPlanning dates back to 2013

Council papers identified a Mairehau/Burwood intersection upgrade more than a decade ago. [1]

Public recordA bus detour from 9 June 2026

Metro lists a westbound Route 7 diversion via Putake Drive, still without a published end date at this review. [14]

Current local updateTraffic lights deferred to later in 2027

The roundabout-to-signals conversion has been deferred, according to the local programme information available to me. [17]

Published testimonyBusinesses have reported disruption

The 2025 consultation contains a local business’s account of repeated roadworks affecting its operation. It is testimony, not a sales audit. [15]

The public timetable has not caught up with the local update.

Council’s consultation page still gives summer 2026/27 as its construction target. The more recent local information is that the conversion has moved to later in 2027. I retain that update here, while making its source clear; a dated public notice confirming the revised programme is not available in the sources linked below. A revised start period also does not establish a completion date. [10] [17]

The roads and the diversion

Putake Drive joins Mairehau Road east of the Burwood intersection and runs north towards Rothesay Road. The earlier schematic incorrectly showed it branching from the roundabout. The corrected diagram follows the connections shown in Metro’s detour map. [16]

Burwood, Mairehau, Greenhaven and Putake Drive — simplified road connections North is up. Putake Drive meets Mairehau Road east of Burwood Road and runs north towards Rothesay Road. It does not branch from the Burwood–Mairehau roundabout. Greenhaven Drive lies west of Burwood Road, linked by Stanford and Newhaven streets to the south. The blue line shows the westbound Route 7 detour via Putake, Rothesay and Burwood roads, with a simplified Burwood Hospital loop and a return through the intersection. Street geometry and distances are simplified; other streets are omitted. ROAD CONNECTIONS · NOT TO SCALE N Rothesay Road Putake Drive Burwood Hospitalentry loop simplified Mairehau Road Mairehau Road Burwood / Mairehauintersection Burwood Road Greenhaven Drive Stanford StreetNewhaven Street Putake joins Mairehau here,east of the Burwood intersection. Route 7 bus detour towards Halswell Tendered water-main corridors
North is up; road shapes and distances are simplified. The bus route returns through the Burwood/Mairehau intersection after the hospital loop. Dashed lines identify the water-main tender corridors, not current excavation or closure locations. Other streets and the exact wastewater alignment are omitted. [4] [16] Open the full-size schematic.

Water works extend onto the adjoining streets

The 2024 water-main tender covers Burwood Road from Mairehau Road south to the pump station at 168E Burwood Road, and north towards Nederland Avenue/Rothesay Road. It also covers Stanford and Newhaven streets between Burwood Road and Greenhaven Drive. This establishes the geographic scope; it does not supply a complete history of traffic restrictions. [4]

Putake repairs overlap the bus-diversion period

Council’s notice schedules initial surface repairs between Puhara Avenue and Titirangi Crescent for 31 August–7 September 2026, subject to weather and site conditions. Final surfacing is a separate stage that Council says may follow up to 12 months later. The notice specifies contraflow traffic, a 30 km/h limit, restricted parking and limited property/workplace access. Footpaths within kerb-and-channel work areas are also to close. These are concrete access constraints, even though the road itself is not listed for full closure. [13]

The dates overlap the published bus diversion. That warrants a question about coordination, but the two notices alone do not measure delays or demonstrate that the detour became unusable.

A bus notice has a specific scope.

Metro confirms the diversion for Route 7 towards Halswell and says its eastbound service is unaffected. The diverted service still returns via Burwood Road and the hospital to the intersection. The notice does not establish the routes taken by all private vehicles or the number of customers passing a shop. [14]

Planning and works: a sourced timeline

Planning dates, funding allocations and construction periods describe different things. This timeline keeps them separate. In particular, a tender award or an annual budget does not establish the start and end of road closures.

The Gantt chart above provides the visual overview. This table separates planning, budgets, notified disruption and locally reported work, so the source and certainty of each period remain visible.

A shop can be open and still be hard to reach

The dairy beside the intersection is central to the local concern. The earlier account describes barriers and traffic management making the shop appear enclosed, with access less obvious and a substantial loss of passing custom. I retain that as a local observation and report, not an independently measured revenue result. [17]

What the consultation adds

The published consultation provides a firmer basis for discussing access. The NZ Spinal Trust’s submission describes difficulties for hospital patients and other pedestrians, and calls for easier access to the dairy and shopping area. Separately, the manager of Mairehau Riding Centre reports that recurring roadworks and restrictions had affected its business and others nearby. [15]

These submissions show that access and business disruption were raised publicly in 2025. They do not establish the dairy’s 2026 turnover, prove the scale of a loss, or demonstrate that roadworks were its sole cause.

Harder to find the entrance

Barriers, changed approaches and temporary signs can make a quick stop feel uncertain.

A less convenient visit

Changes to parking, turning movements or walking routes can add time and effort.

Fewer unplanned stops

Some customers may choose another shop. This is a plausible mechanism, not a measured result for this dairy.

Council’s consultation describes roughly 8,000 vehicles a day at the intersection. That is background traffic context from the consultation, not a current traffic count, customer count or basis for estimating lost sales. [10]

What would establish the business impact more clearly?

Comparable weekly sales and transaction counts, dated photographs of access arrangements, changes to parking, and a record of construction stages would help. Seasonal patterns and other influences on trade would also need to be considered. No such sales dataset is included in this review.

The coordination question remains

The named transport, water and wastewater projects appear in public planning and funding records. Their routes overlap or feed the same intersection. My assessment is that this is enough to ask how the cumulative disruption was considered across the corridor. It is not enough to conclude that the work could all have been done under one contract, or that repeated excavation was necessarily avoidable. [3] [4] [6]

Asset condition, underground-service conflicts, contractor availability, approvals and the need to keep services running can constrain sequencing. These are possible considerations, not explanations established for this project. The records linked here do not show which constraints drove each local decision.

There is a relevant Council comparison

In its 11 November 2025 Harewood Road update, Council described transport and water teams coordinating their work to reduce repeat disruption. It also planned intensive work during the January holiday period to shorten the programme. That is a useful example to ask about here; it does not prove the same approach was technically feasible at Burwood/Mairehau. [12]

What can reasonably be concluded

The record describes multiple projects on a shared network, with a local history of repeated disruption and a reported further intersection stage later in 2027. Nearby businesses and residents experience their combined effects. The unanswered issue is how that experience was weighed when the works were planned and rescheduled.

The reported extra wastewater damage may explain a change to a particular stage, but the material reviewed does not establish when that defect became known. Nor does it establish a final date for unrestricted traffic. A suggestion that work could continue into 2028 would therefore be speculation, and is not presented as a forecast here.

Questions worth putting to Council

These questions follow from the available evidence. They seek the decisions and delivery constraints behind the programme.

  1. Publish the revised programme.What are the current start window, expected duration and completion target for the traffic-light conversion now deferred to later in 2027? When will the public project page be updated?
  2. Explain how the projects were coordinated.What joint sequencing assessment covered the Mairehau corridor, Burwood-area water mains, wastewater renewal, power relocation and intersection rebuild? What prevented closer integration where the work areas overlap?
  3. Account for works on the diversion route.How were the Putake Drive repairs between Puhara Avenue and Titirangi Crescent coordinated with Metro’s diversion? What arrangements kept buses and other road users moving?
  4. Show how shop access was protected.What arrangements maintained visible entrances, safe pedestrian and wheelchair access, deliveries and practical short-stay parking for the dairy and neighbouring shops through each stage?
  5. Assess the cumulative business effect.What business consultation and monitoring occurred across successive projects? What responses, access improvements or support were considered when businesses reported disruption?
  6. Explain the additional wastewater work.When was the reported extra damage identified, how did it change the scope and timetable, and which later stages depend on its completion?

These questions have not been sent to Council as part of this review.
