• TSNZ was formed in 2007 and specialises solely in the hire and sale of purpose designed and built excavation shoring equipment. TSNZ has developed solutions for open pit shoring as well as trench shoring.
  • TSNZ has proprietary mechanical shoring systems sourced directly from the German manufacturer LTW.
  • In addition, since early 2013, TSNZ offers hydraulic brace and sheet shoring sourced from specialist MGF UK Ltd.
  • The experience TSNZ has gained since 2007, and it’s sole focus on excavation shoring, has positioned the company as New Zealand’s market leader in the field.


TSNZ’s head office is located in Auckland at 1 Sylvia Park Rd, Mt Wellington and our yard is at Cnr Great South Rd & Inlet Rd, Takanini. In Christchurch TSNZ has a yard and office at Cnr Johns & Sawyers Arms Rd, Harewood.

Equipment Sales

Trench boxes, manhole boxes and trench sheets are available both new and refurbished. Some new equipment is carried in stock but for large orders lead time for supply of new equipment from Europe is typically four months. Re-furbished trench box equipment is available for sale from time to time, which is usually available within a week ex Auckland.

For slide rail purchases sufficient lead time is required as this equipment is manufactured to order in Europe. GRiPSHORE is stocked by TSNZ in Auckland in limited quantities. For large orders GRiPSHORE will need to be shipped from the UK which will require a lead time of approximately 10 weeks.

TSNZ provides support to customers for:
