Rangiora Aeration Basin

The Contract Works involved the construction of a new earth wastewater treatment aeration basin at the Rangiora Wastewater Treatment Plant (WWTP). The site was an active wastewater treatment plant and the contract works were carried out at the same time as other significant construction works to construct a new inlet pump station and screening channel.

Existing pipelines had to be protected and remain live throughout the period of the contract works. Temporary bypassing pumping and pipework was required to maintain a live network/plant.

Evans Pass Road Retaining Wall

Two retaining walls were constructed on Evans Pass Road under subcontract to  McConnell Dowell.

McConnell Dowell have the contract to make Evans Pass Road safe and reopen it to traffic from Lyttelton to Sumner. The retaining walls were constructed to strengthen two areas of the road which had subsided badly and had limited capacity during the Canterbury earthquakes.

Voelas Rd Inlet

Hunter Civil undertook the upgrade of an old brick barrel inlet structure in Lyttleton. The project invloved delicate excavation around the existing brick barrel, complex formwork to achieve the curved shape for the new inlet, and management of flow into the existing inlet.

The project was completed in 4 weeks, exactly on time and within the client's budget.


The Reserve Terrace Retaining Wall Rebuild is a technical and challenging project for the replacement of a damaged stone retaining wall.

An innovative solution requiring the use of a temporary works platform to support the drilling and excavation plant was required. Hunter Civil provided key inputs into the design and methodology for the temporary works. The temporary works platform was in part connected to the permanent works.

Darfield Skatepark Completed Work

SDC Skate Park Upgrades

Hunter Civil constructed extensions to the Leeston and Darfield skateparks for the Selwyn District Council at the request of the community. Both skate parks included a significant amount of flat areas, and several features including quarter pipes, wedges, hubbas and skateable seats. The project was carried out by an experienced crew in 8 weeks. It was delivered on time, budget and exceeded the client's expectations.

Radcliffe Culvert Extension

This project involved the extension of the existing historical culvert while working around live traffic and preserving a historical arch. One of the biggest challenges to this was carrying out work with heavy plant, while maintaining a live road as this was the only heavy haulage route in and out of Lyttleton.

Moore St Pump Station

A new wastewater pump station was constructed in Kaiapoi. The project involved a 5.8m deep, 2.5m wetwell construction in a high water table environment within the Kaiapoi Red Zone. The construction method included an 8m deep sheetpiled cofferdam, wellpoint dewatering, PE pipe welding laying. All of this was done while working around existing services.
Moorehouse Bridge Abutment Wingwall

Moorehouse Overbridge Strengthening and Repairs

Hunter Civil was subcontracted by Downer to undertake this vital SCIRT project in 2015. The project involved pouring over 200 tonnes of concrete, fixing over 35 tons of reinforcement, and the use of a wide range of skills and techniques to pour self leveling concrete overhead and in difficult access areas under the bridge.

Invercargill Skate Park

This project involved the removal of the existing skatepark, the installation of a new drainage system; a new lighting and power system to enable night time use of the skate park and new CCTV facilities.

Ouruhia Radio Mast

Ouruhia Radio Mast Foundation Remediation

Following the September and February Canterbury Earthquakes, the 137m high radio mast foundations settled significantly and rotated. This was a consequence of lateral ground spreading and liquefaction.  The remedial work required stabilisation of the 48 tonne mast and re-tensioning of the guy rope system.

DoC's Fox Glacier Splash Ford Replacement

This project was undertaken within the Westland National Park, where specific requirements catering for both variable weather conditions, and risk management of flash flooding and rock-falls were put in place.

Owenga Wharf Replacement, Chatham Islands

This large and challenging contract was undertaken by the Hunter Civil/Makeri Construction Joint Venture in mid-2009 to replace the Owenga Wharf on the Chatham Islands. Aspects of this contract were very challenging due to its location. Not least of the challenges were the logistics of supplying the required resources across an 800km sea journey. Additionally the weather and sea conditions required a precise focus on the constructability on a day to day basis.

Hunter Civil

Mount Cook Sewage Treatment Pond Stage 2

This contract was undertaken by Hunter Civil during winter at the Mt Cook/Aoraki village. Weather conditions (particularly the heavy snow and constant freeze/thaw conditions) made this job very challenging at times. A large dumping of snow mid-way through the project added to the complexity and challenges we faced on the ground.
