Waka Kotahi NZ Transport Agency is investigating long-term improvements in the safety, reliability and connectivity of SH1 between Cambridge (from the end of the Waikato Expressway) and Piarere (at the intersection of SH1 and SH29).
The purpose of the project is to investigate long-term improvements in the safety, reliability and connectivity of SH1 between Cambridge and Piarere.
The State Highway 1 (SH1) Cambridge to Piarere Long Term Improvements Project is a 16km long four-lane expressway extending from the southern end of the Cambridge section of the Waikato Expressway to the intersection of SH1 and SH29 at Piarere.
The Board endorsed a business case in June 2021 and we are now progressing to protect the preferred route. This involves processes under the Resource Management Act (RMA) to allow Waka Kotahi to require designations and to obtain regional resource consents to ensure we are ready to proceed if and when funding is made available.
Once route protection is secured, funding must be confirmed (see points below). Then the next stages include detailed design, tendering and construction.
Funding for a new roundabout at the intersection of SH1 and SH29 in Piarere was announced in 2020 as part of the NZ Upgrade programme.
Following this, work was undertaken to complete the detailed business case looking at the long-term strategic route between Cambridge and Piarere, which had been put on hold for re-evaluation in 2018.

The earlier work was reviewed, updated, completed and presented to the Board.
CloseThe indicative alignment for the proposed expressway broadly follows the existing SH1, from the end of the Waikato Expressway to Karapiro Road. Near Karāpiro Road, the alignment deviates onto a new offline corridor that sits approximately 1km north of the existing SH1 and ends at the SH1/SH29 intersection.

The key components currently being proposed are:
The next step, which is where the project is now, is to secure route protection. This involves processes under the Resource Management Act (RMA) to allow Waka Kotahi to require designations and to obtain regional resource consents to ensure we are ready to proceed if and when funding is made available.
Once route protection is secured, funding must be confirmed (see points below). Then the next stages include detailed design, tendering and construction.
Route protection of the preferred route entails Waka Kotahi completing a concept design. To create the concept design, there is a lot of detailed work underway in areas such as identifying and addressing environmental effects including ecological, landscaping, urban design, groundwater, archaeology, air quality, vibration and noise. This will result in a number of design plans which will form part of the Notices of Requirements (NOR) and consent applications.
Based on those concept designs, Waka Kotahi will seek consents and notify its requirements for designations under the RMA.
In May 2022, the preferred road alignment was shared with affected landowners.
CloseThe public will have the opportunity to see the design plans and to discuss the project with members of the team before the required documentation is submitted to the councils.
CloseWaka Kotahi will then proceed to finalise the required documentation for protecting this route for the future.
Notices of Requirement (NoRs) will be lodged with Waipā District Council and Matamata-Piako District Council. At the same time, Waka Kotahi will lodge resource consent applications with the Waikato Regional Council.
When we lodge these, we will request that they are publicly notified. This means that any member of the public can make a submission to the councils with respect to the notice of requirement or the consent applications and participate in the process.
We will update everyone on our email database and through a website update when we have a definite date as to when lodgement will be.
CloseNo funding has yet been allocated for construction of the 16km expressway between Cambridge and Piarere and is not expected until later in the decade. However, route protection is a very important step to ensure we are ready to proceed if and when funding is made available.
The total cost of the project is estimated in the detailed business case to be approximately $635m. There is no funding available in the National Land Transport Programme (NLTP) to prioritise this project for detailed design and construction before the 2027–2030 period.

CloseWe are also now developing the detail of the walking and cycling component of the Detailed Business Case (DBC) for Cambridge to Piarere. This addition will better align the project with government priorities.
Recently the Government’s Emissions Reduction Plan was released. It calls for a 41% reduction in emissions from the transport sector by 2035 (from 2019 levels). Waka Kotahi’s role is to ensure road and transport corridors are fit for the future by including a greater range of transport choices.
To be funded, any transport projects must demonstrate how they will contribute to or be consistent with emissions-reduction objectives. Other transport choices such as walking and cycling need to be included in any transport planning such as the work we are doing on the future of State Highway 1 between Cambridge and Piarere.
One of the overall objectives is to allow for connection to other shared pathways in the area including the Te Awa Trail, the Hauraki Rail Trail (north of the new SH1 alignment) and the Waikato River Trail (at Horahora Road).
Such facilities help make our towns and cities more accessible, provide tourism opportunities, reduce traffic congestion and greenhouse gas emissions, support people to be active and contribute to healthy communities.
As with any major transport projects, before funding can be sought for shared pathways for example, there needs to be investigations into how these connect to other pathways and transport hubs to provide wider transport networks, the safety of those pathways, how attractive they are to potential users, feasibility of constructing, maintaining and operating the pathways and any cultural and environmental effects.
Working closely with our partners and using some of the criteria mentioned above, we have identified four possible routes to consider for a new shared path between Cambridge and Piarere. One is alongside the proposed Cambridge to Piarere expressway and the others are closer to Lake Karāpiro. We have discussed the possibilities with landowners who may be affected and also the local community.
You can find the results of our engagement with stakeholders and the community in our engagement report.

The information obtained through recent engagement, as well as the multi-criteria assessment used on the possible routes, will be used to inform the final decision on the preferred route. The decision on this should be released in the next few months. No funding is currently allocated to this project.
