Deconstruction is the selective disassembly of buildings and structures so materials can be recovered, repurposed, recycled, reused. It provides an environmentally sustainable solution to the construction sector.



Construction in the housing and infrastructure sectors is continuing to grow rapidly in New Zealand. Often, before construction can begin, existing structures must be demolished and most of these materials end up in our landfills.

TROW Group, a proudly Pasifika-owned and Pasifika-led company, offers a sustainable alternative. Instead of demolishing buildings and structures, TROW Group deconstructs them and upcycles more than 90% of all salvaged materials.

Increasingly, the construction sector is under pressure to support the Government’s environmental targets, and local council initiatives such as Auckland Council’s ‘Zero Waste by 2040’ programme. TROW Group is your expert deconstruction partner and can help you achieve your commercial objectives while reducing your impact on the environment for the benefit of all New Zealanders.

TROW Group’s expertise includes:

  • commercial, industrial and residential deconstruction of single and multi-level sites
  • certified asbestos consultancy including testing, monitoring and removal
  • partial or full demolition
  • internal deconstruction or demolition.
