About Us

Pacific Corrosion Consultants (PCC) is a division of LTH Ltd, the umbrella company for a number of specialist consultancy teams with its foundation in the power engineering field.

LTH Ltd was renamed from LineTech Consulting Limited in 2016. LineTech Consulting was founded in 2004 with a merger of Linelink Ltd and Power Line Solutions (NZ) Ltd. The original Linelink company was founded in 1994 as a result of the privatisation of the electricity industry in New Zealand.

In the early 1990s Wal Marshall and Mike Boardman, now both Directors of LTH were instrumental in developing the Transpower transmission tower painting refurbishment program. The work included developing process methods, specifications, training and Contractor development. Now, some 25 years later, the tower structure maintenance program is Transpower`s largest area of expenditure.

The PCC team has since grown to be the largest independent 3rd party coating inspection group in New Zealand. With around ten staff with ACA and NACE certification.


Whilst the servicing of the transmission tower work has been our mainstay, through our reputation, we were developing a market outside transmission tower assets, predominantly infrastructure. With this ever-expanding client base, it was decided we needed a platform that reflected the broader capability and experience of corrosion and coating consultancy both in New Zealand and the wider Pacific area.

This came at a time when there is increased public scrutiny of infrastructure asset management and the demand for reliability, durability and on-going safety expectations.

By providing our clients with easily understood, comprehensive advice and assessment information we have been able to secure on-going business relationship with many of New Zealand`s major asset owners.
