Environment
Helping clients navigate risk, approvals, and responsible development.
BTW’s environmental scientists and ecologists provide practical advice, technical expertise and clear guidance on environmental projects where environmental considerations, construction realities, regulatory requirements and long-term outcomes must be carefully balanced.
Working alongside BTW’s planning, surveying and engineering teams, we provide integrated environmental support from early feasibility and consenting through to construction, monitoring and ongoing management. Our team helps clients make informed decisions, manage environmental responsibilities and support positive long-term outcomes for both projects and communities.
Why choose BTW Environment:
Our team understands how environmental considerations interact with infrastructure delivery, construction methodologies, consenting pathways, restoration goals, and long-term operational requirements. This helps clients identify risks early, reduce delays and make informed project decisions.

- Practical environmental advice grounded in real project delivery, not just reporting.
- Environmental management plans, monitoring and reporting that support compliance, risk management and keeping projects on track whilst protecting human health and the environment.
- Capability spanning ecology, contaminated land and asbestos surveys, and water services.
- Certified Environmental Practitioner (CEnvP) expertise within the team.
- Experience across infrastructure, land development, energy, industrial and public sector projects.
- Integrated support across planning, engineering, surveying and environmental disciplines.
- Regional knowledge and experience with nationwide delivery, strong council relationships, and proven partnership with mana whenua across New Zealand.
BTW works across diverse and often challenging environments, from alpine terrain and wetlands to urban waterways and infrastructure sites. One day may involve monitoring aquatic species in an awa, the next supporting contaminated land investigations, waterway daylighting, or material reuse initiatives that contribute to the quality and character of public spaces. We are trusted environmental advisors on complex projects.

Environment – Your questions answered
An ecological survey is a structured assessment of habitats, flora and fauna to identify ecological values, potential effects and required mitigation. Often required for planning and resource consents, our ecologists ensure assessments are practical and robust to support our environmental planning assessments.
Environmental requirements vary depending on the site, proposed activity and local rules and regulations. Our team helps identify risks early and advises on the assessments, monitoring and or management plans needed to support approvals and reduce delays later in the project. An environmental assessment demonstrates how potential effects will be managed under New Zealand’s consent frameworks.
