After being put through a rigorous selection process, in early 2017 Greaves Electrical was awarded the 3 year master services agreement for electrical services at Contact’s Stratford Power Station.
This contract involves supplying electrical support to Contact for all their electrical systems from high voltage maintenance, instrumentation, site services maintenance to project works.
We also work in closely with Contact providing labour and assistance for their major maintenance shutdowns.
Waitangi Fish Factory - Chatham Islands
Aotearoa Fisheries is the largest Maori-owned fisheries company in New Zealand. They engaged with Peter Swan Ltd consulting engineers on the rebuild of their processing factory at Waitangi township on the Chatham Islands, to handle the design and project management of the new factory. The new factory has export capabilities and is designed to not only process fish, paua and lobster but also to stand up to the harsh island environment.
Greaves Electrical won the tender to supply and install the electrical services for the new factory, from the logistics of getting materials and people to the island, generator connection, switchboards, lighting, data and general power right through to the electrical for the refrigeration plant. A team of five relocated from Taranaki to the Chatham Island for five weeks to complete the install.
““Greaves provided a quality installation for a harsh working environment on an isolated site, on time and on budget.”

ANZCO is one of New Zealand’s largest exporters, has sales of NZ$1.3bn and employs over 3,000 staff worldwide.
In 2014 a Taranaki Regional Council project to bolster the Waitara river flood defences created three issues for ANZCO. The first issue was new flood defences called for the construction of a 700m flood wall that ran directly through one of their 11KV sub stations. The second issue was ¾ of the site 11KV network was on legacy Magnafix switchgear which raised genuine reliability concerns with the site engineering team. The third issue was that the site had to keep up with production and couldn’t be shut down to install new equipment.
Greaves Electrical were called to design and engineer a solution to move the substation, replace the ageing equipment and keep the plant going.
A solution was proposed and accepted. This involved the design, planning, construction of a new 11KV switch room complete with transformer bays and 2 new 3.3KV motor starters, installation of a ring main connection cable, removal of the old Magnafix switch gear, installation of new switch gear, testing, commissioning, livening and as-built drawings.
The installation was completed with minimal down time using a combination of staged installation, back feeds and temporary generation meaning the factory could keep producing.
“The solution Greaves have provided gives me peace of mind that the plant will have a reliable power supply for the next 20 years. All the installation has been completed on time with hardly any plant downtime, which is important to us here at ANZCO.

Early in 2014 Greaves tendered to Tetra Pak for the electrical installation of two new Reverse Osmosis (RO) plants at Fonterra’s Longburn factory, in which we were successful.
RO is the tightest possible membrane process in liquid separation. It concentrates the total solids, and only water can pass through the membrane; all dissolved and suspended material is rejected. Fonterra use this Tetra Pak technology to increase efficiency when transporting milk to their production sites.
One of the biggest challenges on this project was the timeline. The plant needed to be completed and commissioned on time as the milk arriving from local farms couldn’t be stopped. To overcome this Greaves mobilized a large team of up to 20 staff to complete the project.
A high standard of workmanship and safety was demanded by the client which was easily covered by our Health and Safety systems and employee training.
