Our Team

Hamish Lowe - Principal environmental scientist

Hamish has specialised skills and considerable experience in managing and undertaking natural resource and infrastructure investigations. This revolves around sustainable land management, wastewater planning, community infrastructure, asset management and farm production systems. He is nationally recognised for his expertise in land treatment of waste material and nutrient management.

In recent years Hamish's expertise has been called on to assist with project management and strategic direction of land development and major resource consent processes. This has involved the bringing together and co-ordination of a range of varying technical expertise. His skill set assists when acting in a Hearing Commissioner capacity.

Rob Potts - Senior environmental engineer

Rob has significant specialist skills in natural treatment systems for both wastewater and stormwater. He has national recognition in the land treatment of wastes, both liquid and solid. This comes from a solid background in irrigation design, soil physics and nutrient management.

Rob’s considerable experience often sees him in the role of managing large infrastructure development projects or acting as a Hearing Commissioner.

Katie Beecroft - Senior environmental scientist

Katie has a multidisciplinary background spanning geology, volcanology, hydrogeology, soil science, soil chemistry, and geochemistry. Her primary work background and interests are in the application of soil science to issues of land management. This includes: land treatment of liquid and solid waste; Soil improvement by ameliorative additions; Contaminated site assessment, management and remediation; and Nutrient management in dairying catchments.


Jacqui Horswell - Senior environmental scientist

Jacqui has a wide range of skills and experience relating to sustainable waste management, particularly in the assessment of environmental effects of land application of biosolids, waste water and greywater. As an environmental microbiologist she has significant expertise in potential environmental and human health impacts of microbial and chemical contaminants in wastes. Her background as a senior research scientist brings an in-depth understanding of emerging issues that face the waste water industry and can ensure that waste management strategies are pro-active and future proofed. She has worked on the development of national guidelines for biosolids management and is a Board member for the Australian New Zealand Biosolids Partnership.


Sian Cass - Environmental scientist

Sian has a sustainable land management background. She is knowledgeable in production systems and resource assessments, contributing to pulling together aspects of larger detailed investigations.


Philip Lake - Environmental scientist

Philip's work has included laboratory water quality analysis, air quality and environmental science, a paint factory, local government resource consent compliance monitoring and enforcement. He has expertise in sampling and environmental assessments of stormwater and wastewater and industrial air discharges; preparing and reviewing resource consent applications, air discharge modelling, and undertaking contaminated sites investigations.


Angela Lane - Environmental scientist

Angela has recently completed a Master of Science in Agricultural Science from Massey University. Her thesis involved undertaking investigations into soil water flow pathways using ground penetrating radar. This research formed the basis of an ongoing project towards minimising nutrient loss from irrigation systems.

Angela holds an Advanced Certificate in Nutrient Management and is proficient with the use of OVERSEER® nutrient modelling. She has a background in sheep and beef farming and understanding of dairy systems, and has been involved with the development of Environmental Farm Plans and nutrient modelling for processing of Land Use and Discharge consents.


Terry Hughes - Environmental scientist

Terry has a Master of Science in Engineering Geology, and is a senior groundwater specialist with over 10 years’ experience in a consulting environment. terry's key skills include aquifer testing, groundwater assessments and AEE (Assessment of Environmental Effects) preparation in conjunction with groundwater consent applications. Other skills include wastewater assessments and preparation of a variety of resource consent applications. Outside of work, Terry enjoys mountain biking for fitness and weightlifting coaching/competition organiser as a hobby.


Peter Hill - Senior advisor

Peter is experienced in managing and undertaking natural resource management and advocacy. Following early science and investigation roles Peter spent a number of years in the local government environment followed by a period of environmental advocacy. More recently he has pulled his combined skills together to manage and coordinate investigations and resource consenting for waste, water and soil related projects.

Brian Ellwood

Brian Ellwood - Senior environmental engineer

Brian has specialist irrigation and infrastructure development experience overseeing the investigation of large scale energy and irrigation projects including: management of large multidisciplinary teams, review and approval of technical reports, environmental management systems, strategic advice, funding applications, expert evidence, and management of stakeholders, communications and contracts and negotiating agreements.
Brian comes from a farming background with a sound knowledge of modern farming systems, so along with his Environmental Engineering training and engineering management skills, Brian has considerable experience in advising on nutrient management issues, including at Land and Water Forum working groups, resource consent hearings, Environment Court mediations and plan change hearings.


Jane Petch - Environmental engineer

Jane has a background in environmental engineering and has previously been involved with resource consent procurement for wastewater and stormwater discharges, irrigation takes, small community onsite wastewater systems and contaminated site assessments. This work has involved data assessment, field investigations, compliance reporting and consent preparation.


Nadine Hall-Lowe - Administration

Nadine is a key member of the behind the scene team, looking after staff needs and coordinating purchasing and payments.


Brenda Fredrickson - Finance manager

Brenda is part of the essential behind the scenes team keeping the office functioning and together. Brenda can help you with inquiries about accounts payable and accounts receivable.
