Camberley Substation's Boosted Capacity Helps Power Local Growth

Press Release – Unison
The substation upgrade is one of four planned for Hawkes Bay under Unisons 10-year Asset Management Plan. Following Cyclone Gabrielle, Unisons Awatoto, Tutira and Esk substations are also lined up for upgrades to improve resilience.
Unison Networks is proud to announce the successful completion of the Camberley Substation rebuild in Hastings, marking a major milestone in powering Hawke's Bay's growing energy needs. The state-of-the-art facility has been fully upgraded to enhance resilience, significantly increase capacity, and support a sustainable energy future for communities across the region.
The newly rebuilt Camberley Substation now boasts nearly four times its original capacity, enabling it to supply electricity to approximately 3,000 residential and commercial customers. This enhanced capacity ensures that Camberley can meet the increasing energy demands driven by ongoing regional development, including critical infrastructure projects such as the Hawke's Bay Hospital upgrades, the Frimley water storage and treatment plant, and electric vehicle fast-charging stations.
The substation upgrade is one of four planned for Hawke's Bay under Unison's 10-year Asset Management Plan. Following Cyclone Gabrielle, Unison's Awatoto, Tutira and Esk substations are also lined up for upgrades to improve resilience. The goal is to ensure Unison's electricity network continues to meet the communities' current and future needs, providing a more resilient and secure supply that supports growth and electrification in the region.
Inspired by Unison's award-winning Windsor Substation, the Camberley rebuild incorporates innovative sustainability elements like advanced cross-laminated timber construction and gas-insulated switchgear that uses dry air insulation and vacuum interruption supplied by RPS Switchgear — a significant step in reducing the environmental impact of substation switchrooms by eliminating the use of potent greenhouse gases.
Unison's General Manager Networks & Operations, Gaganpreet Chadha, expressed pride in the project, stating, 'We're proud to be at the forefront of cutting-edge technology and innovative solutions with the Camberley project, and its completion takes us one step further to delivering on our vision to enable a sustainable energy future.
'The success of Unison's award-winning Windsor Switchroom set a strong benchmark, and it's great to follow that up by applying what we learned to the Camberley project. This upgraded facility strengthens our network to better serve Hawke's Bay, not just for today but for generations to come.'
The Camberley rebuild reflects Unison's dedication to not only meeting current energy needs but also enabling the transition to a zero-carbon future. By supporting decarbonisation efforts — such as enabling households to adopt sustainable energy systems and electric vehicles — the substation plays a vital role in fostering environmental progress across the region.
Mr Chadha commented, 'We are continuously optimising our designs for security and sustainability and making improvements as we upgrade substations across our network. Camberley exemplifies our commitment to a building smarter, stronger, and more resilient electricity network that supports secure supply alongside decarbonisation efforts.'
Unison Networks is proud to celebrate this milestone and looks forward to continuing to power progress for Hawke's Bay and beyond.

Inland Revenue finds $45 million of undeclared tax in horticulture industry from last 10 months

Inland Revenue was pursuing the contracting firms through audits and prosecutions with nearly 100 such audits active at the moment. Photo: Supplied Inland Revenue has found $45 million of undeclared tax in the horticulture industry in just the last 10 months. Spokesperson Tony Morris said they were seeing concerning practices in the sector, that included people being paid under the table. He said some in the sector were still recovering from Cyclone Gabrielle, and dealt with increasing compliance costs and labour shortages, so paying tax could become an afterthought. Morris said Inland Revenue was also seeing cash sales not being reported correctly and withholding tax not being deducted on payments made, deducted at incorrect rates or not being reported. Growers typically hire labour through contracting fims and Morris said it's these firms that try and hide payments. Photo: 123rf Inland Revenue was pursuing the contracting firms through audits and prosecutions with nearly 100 such audits active at the moment. "While many growers are doing things right, they typically hire labour through a contracting firm, which then frequently pays the labourers in cash. Some of these contracting firms then use convoluted business structures to try and hide those payments," Morris said. "Not only does this mean they could avoid their tax, but it also means the labourers can get benefit payments they aren't entitled to or avoid their child support or student loan payments. "Inland Revenue is cracking down on this by requiring many contracting firms to withhold tax from their labourers payments, and pay that directly to IR. Where Inland Revenue identifies growers and other payers not correctly deducting or accounting for the tax, we are also following these up." Morris also said due to the high use of cash and migrant labour in the horticulture industry, it was a sector open to the abuse of workers. He said Inland Revenue worked with other government agencies to address such issues. "Alongside Hort NZ and Zespri, we work hard to ensure growers and contracting firms are aware of what they need to do to get things right, and appreciate the efforts of the many who do get it right."

Farmers Still Rushing To Convert Land To Forestry

, Producer/Presenter Whole farm-to-forest conversions continue, according to a new report released by Beef and Lamb New Zealand. The research, carried out by Orme and Associates on behalf of Beef and Lamb, found close to 40,000 hectares of sheep and beef farms had been sold for forestry since September last year. The report also confirmed 29,518ha had sold in 2023 and 30,483ha in 2024. It brings the total amount of farm-to-forestry conversions since January 2017 to more than 300,000-ha. Beef and Lamb estimates this has resulted in the loss of more than 2 million stock units since 2017. Chair Kate Acland said the data underpinned longstanding concerns about whole farm-to-forestry conversions. "The numbers show whole-farm sales for conversion to forestry for carbon credits are continuing at pace," she said. "What we're really concerned about is whole farms, really good productive land getting planted into trees." The research showed Hawke's Bay, Wellington and Wairarapa remained preferred locations, while Southland had also seen a notable increase. There was a significant slowdown in the Gisborne region, likely due to the environmental impacts of adverse weather events such as Cyclone Gabrielle and tightened harvesting conditions being set by regional councils. Acland said they were not against incorporating forestry within farms, adding if most farmers planted 10 percent of their least productive land in trees, they could still maintain production. "We're very supportive of incorporating trees within farms. and I think there's a real opportunity here for farmers to be part of the solution." This week the government introduced new legislation to restrict farm-to-forest conversions on Land Use Classification (LUC) 1-6 land. Under the changes, which will retroactively take effect from December last year when the policy was originally announced, up to a quarter of farms can be planted in forestry for the Emissions Trading Scheme (ETS). There will also be a ban on full farm-to-forest conversions entering the ETS for actively farmed land and an annual cap of 15,000ha for forestry entering the ETS for lower quality farmland. Acland said while the government putting restrictions around whole farm to forest conversions was positive, she wasn't sure it went far enough. "Anecdotally we're still hearing of a significant number of farms being sold this year, despite the government announcing the limits last year. "We're concerned that some sales are continuing on the basis of intent to purchase land before the limits were announced. We urgently need the government to tighten the criteria around proof of intent to purchase." Additionally, she was particularly concerned about class 6 land, which she said was "some of the most productive sheep and beef breeding country". Acland said carbon forestry had a comparatively "short-term return" when compared to sheep and beef. "I think we need to recognise the importance of the red meat sector for the economy of this country." Federated Farmers national president Wayne Langford echoed some of these concerns, saying the country was approaching critical mass for sheep production. He said the new forestry conversion rules were moving "slowly". "We're gonna see more processing plants close, we're gonna see a lot more communities close down unless we do something about this issue across the country." The legislation is now before Parliament and is to come into force October 2025.

Transpower Proposes Further Investment In Power Supply For Hawke's Bay

Once the Commerce Commission approve the proposal, Transpower expects to start the work in October 2026 and finish by December 2027. Transpower plans to invest $47.0 million to rebuild its Redclyffe substation to better protect Hawke's Bay's electricity supply against flooding and earthquakes. The national electricity transmission grid owner submitted a proposal to the Commerce Commission today for approval to rebuild the main 220kV switchyard on the existing site, raising essential equipment out of the reach of potential flood waters. Transpower's Executive General Manager Grid Development Matt Webb said this is another aspect of the work to rebuild the substation after it was flooded during Cyclone Gabrielle in February 2023. 'After Cyclone Gabrielle, we made a commitment to the people of Hawke's Bay to make their region's power supply more resilient to extreme weather and seismic events,' he said. 'Residents can be confident that our interim upgrades have protected their power supply, and the work we're proposing now will make Redclyffe substation flood resilient to a 1-in-450-year flooding event and much more resilient to earthquakes. 'For the people of Napier, Hastings and surrounding areas, that would mean the power is more likely to stay on during catastrophic weather events like Cyclone Gabrielle.' Mr Webb said Transpower has already completed significant work at Redclyffe substation to improve security of supply in the region since Cyclone Gabrielle. Interim upgrades to the 110 kV switchyard were made in 2023 to make the equipment there more resilient to flooding, and an interim 220 kV control room has also been installed above the flood level. A new 220 kV/110 kV interconnecting transformer is currently being installed that will significantly boost reliability of electricity supply in the region. Under New Zealand's electricity transmission regulatory framework, the Commerce Commission reviews and approves Transpower's work plans to ensure investment is cost-effective and in the long-term interests of New Zealanders. 'We've engaged extensively with local communities on our plans for the region alongside our local lines company partner Unison Networks,' Mr Webb said. 'We believe this is the most cost-effective approach that also takes into account growing demand for electricity in the region. We have strong support from key stakeholders for our proposal and we look forward to the Commerce Commission rigorously testing our plans and costings.' Once the Commerce Commission approve the proposal, Transpower expects to start the work in October 2026 and finish by December 2027. The work can be completed without any impact to local electricity supply, Mr Webb said.
