Congratulations to the Finalists:

Terre Nicholson Contaminated Land & Groundwater Management Emerging Professional

  • Sandra Hamler – SLR Consulting

Sandra Hamler is a highly valued contaminated land consultant who delivers consistently high-quality fieldwork, reporting, and stakeholder coordination. Working across PSI, DSI, and acid sulfate soil investigations, Sandra demonstrates exceptional care, organisation, and technical rigour.

Sandra is nominated for her ability to support complex site investigations through meticulous planning, clear communication, and reliable data collection. Her work has reduced delays, avoided resampling, and supported cost-effective decision-making for clients operating in sensitive environments.

Beyond project delivery, Sandra actively shares knowledge through industry presentations, internal training, and mentoring. Her commitment to safety, sustainability, and practical learning is helping raise standards across contaminated land and groundwater management practice.

  • Charlotte Rayner – AECOM New Zealand

Charlotte Rayner is an Environmental Scientist who has quickly become a trusted advisor in contaminated land management. With strong technical capability and excellent client engagement skills, Charlotte consistently delivers work that improves environmental outcomes while avoiding unnecessary cost and waste.

Charlotte is nominated for her leadership in closed landfill compliance monitoring, where she identified that many discharge consents were no longer fit for purpose. By reviewing and updating consent conditions, she transformed monitoring from a tick-box exercise into a meaningful risk assessment tool, improving data quality and decision-making for councils.

Her impact extends to industry capability through conference presentations, mentoring junior staff, and enabling new approaches such as laboratory-based rapid screening for acid sulfate soils.

Charlotte’s work demonstrates how thoughtful, evidence-led practice can lift standards across contaminated land management.

  • Oliver Tate – GHD


Oliver Tate is an emerging contaminated land professional known for his strong field leadership, analytical thinking, and commitment to sustainable outcomes. His experience spans complex infrastructure, defence, and mining-related projects, where he consistently supports responsible materials management.

Oliver is nominated for his contributions to major site investigations and soil disposal assessments, ensuring contaminated material is correctly classified and landfill capacity protected. His work on mine tailings reprocessing and water balance modelling demonstrates how environmental risk can be reduced while enabling resource recovery.

Through active involvement in ALGA’s Emerging Professionals SIG, mentoring students and graduates, and sharing technical insights via webinars and industry events, Oliver is helping build the next generation of contaminated land practitioners and strengthen sector-wide knowledge.

WasteMINZ + ALGA Legend

  • Michelle Begbie – Waikato Regional Council

Michelle Begbie is widely respected across Aotearoa New Zealand and Australia for her leadership in contaminated land regulation and policy. As a senior regulatory practitioner, Michelle has played a pivotal role in bridging the gap between regulators, practitioners, and researchers, helping the sector navigate complex technical and policy challenges with clarity and balance.

Michelle is nominated for her long-standing commitment to advancing good risk management practice. She has led cross-Tasman conversations on mandatory reporting, supported regulator-only forums for ALGA, and represented Aotearoa internationally through the Common Forum initiative connecting environmental regulators across Europe and Australia. Her willingness to share regulatory insight has strengthened trust and understanding between regulators and industry.

Through webinars, conference sessions, and working groups with WasteMINZ, ALGA, and the CEnvP Scheme, Michelle has influenced policy discussions and supported better decision-making across the sector. Her impact lies not only in technical expertise but in her ability to connect people, translate science into practice, and leave a lasting legacy of shared knowledge and collaboration.

  • Mark Roberts – Auckland Council

Mark Roberts is widely regarded as one of New Zealand’s most influential leaders in construction and demolition (C&D) waste minimisation. Through his role at Auckland Council, Mark has been a relentless advocate for practical, evidence-led change in how the sector approaches waste, reuse, and recovery.

Mark is nominated as a Legend in recognition of more than a decade of leadership that has shaped national thinking on C&D waste. He has initiated landmark research projects, chaired the WasteMINZ C&D Working group, and driven campaigns such as Construction Waste Week to raise awareness and inspire action. His work during storm recovery has embedded house relocation and deconstruction as preferred outcomes, delivering significant reuse and material recovery.

Mark’s impact reaches across government, industry, and the community. By connecting people, championing collaboration, and turning data into action, he has helped move C&D waste from a niche concern to a central part of New Zealand’s waste minimisation conversation.

  • Sam Willis – Alliance

Sam Willis is recognised as a leader in vapour and gas risk assessment, known for challenging conventional approaches and promoting smarter, more sustainable decision-making. As Environmental Team Lead in Alliance’s Sydney branch, Sam combines deep technical expertise with a strong commitment to mentoring and industry service.

Sam is nominated for his tireless contribution to industry upskilling through ALGA. As Co-Chair of the Vapour and Gas Specialist Interest Group, he helped deliver major symposia, webinars, and training events that have lifted practitioner capability and encouraged the use of multiple lines of evidence in risk assessment. His presentations consistently advocate for proportionate responses that avoid unnecessary remediation and environmental harm.

Beyond formal roles, Sam is a passionate mentor who encourages emerging professionals to step into industry forums, events, and leadership opportunities. His impact is seen in stronger technical practice, better collaboration between government and consultants, and a more confident, sustainability-focused contaminated land sector.
