90+ years of valued contribution

It’s been over 90 years since the foresight and vision of a few enterprising Dargaville individuals led to the establishment of the North Auckland Electric Power Board in 1930.

Here are some of the key milestones and achievements over the years.

1930's

The North Auckland Electric Power Board (NAEPB) was formed in July 1930 to construct the electricity network for our region. After initially renting office space in Dargaville, a permanent building was constructed in 1938 to house administrative and engineering staff.

The first power lines were constructed from Mareretu – Paparoa to Dargaville, then further extended to Maungaturoto to power the dairy factory.

In 1937 the Kamo Town Electricity Board merged with NAEPB.

1940's

The outbreak of World War II caused material and labour shortages impacting growth. Many materials were diverted to the war effort, and the Government impounded NAEPB supplies, releasing only those essential to production.

It was difficult to find workers during this time, and the NAEPB was largely operated by a small number of skilled staff and farmers who needed the power supply. Despite these challenges, the network grew and by 1945 there were over 5,000 consumers connected for a maximum demand of 4,881kW.

1950's

The mid-1950’s saw NAEPB connect its 10,000th consumer – a milestone which was celebrated by presenting a silver tea service to the lucky Onerahi customer!

This decade also saw further expansion to the Dargaville Head Office through the construction of a new engineering division facility, a power pole manufacturing plant and an in-house boardroom.

1960's

Marsden Point was chosen as the location for Aotearoa New Zealand’s oil refinery, and NAEPB were responsible for the electricity supply, powering the plant when it opened in 1964.

The first modern computer was purchased to replace aging bookkeeping machines.

1970's

In 1974 the head office was moved from Dargaville to our current Otaika location in Whangārei.

NAEPB began administering a government loan initiative to insulate homes to conserve energy.

The first company computer system was installed.

1980's

The NAEPB celebrates 50 years, and the early eighties saw increased economic growth in the region.

A new 33kV line was constructed to supply Northland Dairy Company’s new $100m milk processing site at Kauri.

Technology advanced further and the latest appliances showcased the advantages of electricity were displayed at the new electricity centre in Whangārei.

Staff were upgraded to the latest tech when afterhours duty staff were provided with telepagers.

1990's

Northpower Limited is born after the NAEPB purchase of the Whangārei District Council Electricity Division for $13 million.

Northpower then purchased the Wairua hydro power station from Golden Bay Cement and the plant becomes fully automated.

The 1992 electricity industry reforms ends electricity retailing at Northpower in favour of network ownership.

A second Transpower owned 50kV line is built to improve security of supply to Dargaville.

1998 Northpower’s contracting business is established and the maintenance contract with Vector is secured.

Wairua hydro power station undergoes a $5.7 million refurbishment, and Northpower’s tree felling and maintenance programme is launched to keep trees clear of power lines.

Mangawhai substation is destroyed by fire – however power is restored in 80 minutes and a temporary substation commissioned in just 12 days.
