Construction

Major earthworks and civil works for the construction of the platform and drilling pads for the production wells. Other activity include forming access ways for construction vehicles.
  • Hours of Work, 7am – 7pm, 7 days a week except on Public Holidays.
  • Night works would be unlikely / small scale (for the Earthworks and Civil Enabling Works).

As most of the work is happening on Top Energy’s property you should not be adversely impacted by the construction. There will be a number of truck and trailer units required to transport the drilling rig to and from the site. This means that there will be increased heavy traffic along the selected routes of SH 1, SH 12 and Ngawha Springs Road during the project setup, construction and close-down stages.

Whangarei company United Civil Construction.

You will need to contact United Civil Construction. For employment enquiries please contact Cheryl Prince –

Civil works started in October 2017 and will be continue over three summer periods from October to April, with completion of civil works in 2020.

Work involves significant earthworks and civil construction to create access ways and platforms for the well sites, geothermal fluid conveyance and power plant. Large volumes of fill material will need to be imported onto the site. Several site plans have been prepared to facilitate the management of erosion, traffic, dust (air quality), contamination and noise.

Well drilling

Iceland Drilling has the contract.

Once the well platforms and water management system is in place in 2020, well drilling will get underway. Two working production wells and 2 reinjection wells are needed.

Typically, the wells will be 1750m deep and be 1.00m in diameter at the surface and 225mm at their deepest point.

Community benefits

Security of supply and reliability will be improved for the whole of the Northland region by making it less reliant on generation from the south and associated transmission through Auckland.

Increasing generation in the region (i.e. close to local demand) will reduce wholesale prices in the region relative to wholesale prices elsewhere, potentially reducing the price consumers pay.

Transmission charges are likely to be reduced and Top Energy is in discussion with the Electricity Authority (EA) about what transmission costs should be payable by our consumers once the power station comes online.

No. You will still buy your power from your electricity retailer. Top cannot be involved in retailing electricity to consumers on its network.

Ngawha hot springs

The Ngawha hot springs are not impacted by this project and are not operated by Top Energy.
