About Us

Originally a two-man operation, Petone Engineering has steadily grown, with a completely modernised plant and machinery. Our focus is always on quality and ways we can improve the service we provide. An important part of demonstrating and continuing to build our level of service are the certifications, accreditations and memberships we hold.
Petone Engineering has significant experience in earthquake strengthening of commercial buildings and apartments throughout the Wellington region. We are frequently called on to provide specialist advice and assistance in this area.
