What Pattle Delamore Partners does

Pattle Delamore Partners (PDP) is a New Zealand-headquartered, privately held environmental and engineering consultancy founded in 1986, operating from offices in Auckland, Wellington, and Christchurch with a workforce of 251-500 scientists, engineers, planners, and advisors. The firm delivers professional services across thirteen discrete service lines including air quality and GHG assessment, contaminated land, three waters (wastewater, water supply, stormwater), water resources, geotechnical engineering, ecology, climate change and sustainability, planning, strategic advisory, tangata whenua advisory, and a Digital Solutions line covering geospatial and remote sensing work.

Revenue is generated on a project-based, fee-for-service basis through competitive tendering for government and local government clients, direct commissions from established relationships, and referrals. Customer concentration is heavily skewed to NZ local councils (Auckland Council, Hawke's Bay Regional Council, Waikato Regional Council, Horizons, Bay of Plenty, Tauranga, Wellington, and others), central government agencies (Department of Internal Affairs, NZTA, KiwiRail, NZ Defence Force), and select energy-sector clients (Meridian Energy, Genesis Energy, Z Energy). PDP has played a role on landmark NZ infrastructure including the Waterview Tunnel, City Rail Link, and the St Marys Bay water quality improvement programme, and is actively contributing to national standards (Āpōpō Asset Valuation and Depreciation Guidelines Edition 3.0, National Trade Waste Management Guidelines).

Underlying technical work includes Bayesian statistical modelling of extreme rainfall, 2D and 3D groundwater modelling, Tuflow hydraulic flood modelling, advanced membrane bioreactor (MBR) wastewater treatment plant design, and GIS-based catchment analysis for PFAS source investigation. The firm differentiates through multi-disciplinary integration, deep New Zealand regulatory familiarity, and a distinctive Tangata Whenua Advisory offering that embeds te ao Māori and mātauranga Māori into environmental project delivery.

Direct peers

• Tonkin + Taylor: Largest NZ-headquartered environmental and engineering consultancy, providing geotechnical, water resources, contaminated land and coastal services. Closest direct competitor across PDP's core three waters, water resources, contaminated land and geotechnical engineering service lines for the same NZ council and central government client base.
• Beca: Major NZ-founded engineering consultancy with extensive water, environmental and infrastructure practices. Competes directly with PDP for council three-waters and asset management mandates, and is a frequent co-consultant/competitor on major NZ transport and water infrastructure programmes.
• Aurecon: Asia-Pacific engineering consultancy with a sizable NZ practice across water, environment, transport and energy. Competes directly on council infrastructure and consenting work (e.g., NZTA/Aurecon Waterview Tunnel — PDP also worked on this programme as a sub-consultant).

Broad incumbents

• WSP: Global professional services firm with a large NZ presence offering environment, water, property and transportation advisory. Overlaps with PDP across council three waters, climate adaptation and EIA but as part of a much broader global portfolio.
• Stantec: Global engineering consultancy with established NZ operations spanning water, environmental services and community development. Directly comparable on water and wastewater treatment plant design and environmental impact assessment for NZ councils.
• Jacobs: Global engineering and consulting firm with significant NZ water, environment and climate adaptation capability. Competes for major NZ central government and council infrastructure programmes, including hydrogeology and consenting work.
• GHD: Global engineering, environmental and advisory firm with a long-standing NZ practice covering water, environment and energy. Directly comparable on council water infrastructure, environmental compliance and resource consenting work.
• Mott MacDonald: Global engineering consultancy with NZ presence in water, environment and transport. Comparable on large NZ infrastructure projects and environmental advisory, including water resources and tunnelling hydrogeology.

Emerging players

• SLR Consulting: Global environmental and advisory consultancy with growing APAC/NZ presence in environmental impact assessment, contaminated land and climate services. Comparable niche overlap on contaminated land, EIA and ESG advisory services.
• ERM (Environmental Resources Management): Global pure-play environmental and sustainability consultancy with NZ operations. Comparable on contaminated land, climate/ESG advisory and consenting support, though limited presence in PDP's core water-resources/three-waters engineering work.
