About Us

Lumen is a leading provider of transmission and distribution line design, asset inspection, asset management, electrical specialist, energy and carbon engineering and civil and structural engineering services across New Zealand, Australia and the Pacific.

Our origins stretch back to 1994, with the privatisation of the New Zealand electricity industry. LineTech Consulting was formed in June 2004 as a merger between Power Line Solutions (NZ) Ltd (PLS) and Linelink Ltd. Linelink and PLS were established in 1994 and 1998 respectively, and both focused on transmission lines engineering and asset management.

In July 2015, LineTech Consulting Ltd was renamed LTH Limited. This signified the continued diversification from transmission and distribution lines consulting to include complementary consulting services for the electrical industry. This included the purchase of RedFox Structural and Seismic Engineers in 2009 and Enercon in 2013. LTH Limited was a company which supported the establishment and operation of small-to-medium sized consulting businesses (divisions) operating in specialist market segments.

In October 2019 we have rebranded as one team under one name, Lumen. 

Lumen has over 40 professionals spread across New Zealand and Australia, including offices in Christchurch, Wellington and Adelaide. Our qualified, experienced team of Engineers and Inspectors can support your project needs from beginning to end.

Our core values are to:

  1. Provide value to our clients.
  2. Benefit existing employees.
  3. Recognise and reward staff based on merit.
  4. Consistently act with integrity.
