Our Team
Cameron Lines : Director
BSc, MSc (hons), CMEngNZ (PEngGeol), MAusIMM
Cameron is an Engineering Geologist with over 25 years of experience in mining/quarrying, land development, and large-scale infrastructure development, specialising in slope instability, materials assessment, natural hazard assessment, cut slope design, overburden disposal and geotechnical risk assessment.
He has spent the best part of the last two decades working on large open cast mining and quarrying projects and specialises in assessment of geotechnical risks in the context of operations in the extractives sector. His roles have included geotechnical designer, peer reviewer, earthworks supervision and provision of geotechnical support for mining/quarrying operations. Cameron has worked extensively throughout New Zealand, with specific expertise in the geology of the Northland, Auckland and Waikato regions. His career to date has also seen him work in Australia, Indonesia, Samoa, Fiji, Sri Lanka and England.

A good understanding of the New Zealand regulatory environment is one of Cameron’s strengths including the ability to present often complex geotechnical issues within the framework of environmental effects. He has provided technical support to Regulatory Authorities when assessing consent applications and has developed and presented geotechnical evidence on behalf of both Applicants and Regional Authorities at consent hearings, plan change hearings and at the Environment Court. He is certified as an independent Resource Management Act (RMA) hearing commissioner.
Cameron is a member of the Australasian Institute of Mining and Metallurgy (AUSIMM), the International Association for Engineering Geology and the Environment (IAEG) and the New Zealand Geotechnical Society (NZGS). He is a Chartered Member of Engineering New Zealand (PEngGeol). Away from work, he plays Presidents Grade cricket, coaches youth cricket and plays an occasional round golf (though plays less than he might like).

"I have been dealing with Cameron for a number of years. He has the rare skill of being able to do technical work and be able to communicate it to non-technical people in a way they understand. I never felt I was just buying a report from him but that I was buying genuine help for my operation."

Tzin Lai : Associate Geotechnical Engineer
BE(Hons), MEngNZ
Tzin has over 10 years of experience in geotechnical engineering, consulting for various public, industrial and land development clients. Through working on projects with these clients, Tzin has developed a deep understanding of a range of geotechnical engineering systems, such as retention systems, ground improvement, earthworks, seismic engineering, and foundations.
He started in his career in the Nelson region, where he developed his geological appreciation for regions with high seismic activity. In his time in Nelson, he was involved in a wide range of civil engineering disciplines, ranging from geotechnical, three waters and environmental projects. He further developed his geotechnical expertise when he relocated to Auckland and was involved in a variety of geotechnical projects. He is adept in building foundation design, seismic assessment of buildings, seismic hazard analysis, landslip remediation, land development, and three waters infrastructure.
Through his experiences in different ground conditions for a range of clients, he understands that there is not a one-size-fits-all solution, and each project has its own uniqueness and requirements. He works with his clients to understand his role and how his expertise could bring value to the projects.
In his free time, he enjoys tramping in various parts of New Zealand and playing badminton.

Alena Saito-Warren : Graduate Engineering Geologist
BSc
Alena is a Graduate Engineering Geologist with an interest in slope instability and site development who is gaining expertise in Northland, Auckland, and Waikato regional geology.
Since joining Baseline Geotechnical in January 2024, she has been involved in desktop assessments, site investigations including field mapping and core logging, development of ground models, monitoring of displacements and groundwater in active landslides and slope stability modelling. Her recent experience has focused on quarries & mines, remedial design for infrastructure and housing damaged by landslides, and commercial developments.
In her free time, she enjoys searching for geocaches and experimenting with new hair colours.
