About Us

Company History

Weldtech CEO Chris Ellenden travelled for nearly 10 years working as an independent contractor on engineering sites throughout NZ, Australia and Papua New Guinea before returning to Invercargill to raise a family in 1999.

His experience on large industrial sites gave him an in-depth understanding of the complex health and safety concerns of the industry both in construction and maintenance modes. As demand increased, Ellenden formed Weldtech Ltd in 2003.

The firm’s first contracts were for on-site maintenance, however, by 2009 the company was doing increasing amounts of prefabrication and spooling and moved to its current 1000m2 workshop at 13 Bond Street Invercargill.


Weldtech is committed to providing a safe and supportive work environment for its team of skilled tradesmen who work both in our workshop and at sites throughout the south.

All staff are offered the opportunity to pursue formal industry qualifications, including training in new and emerging composite technologies.

From time to time we have vacancies for skilled engineers. If you’d like to be considered for a vacancy, please complete the online application form and upload a copy of your CV.
