Frank Wallwork


ME (Chem & Mats), Dip Dairy Sci. and Tech.

I started as a Technical Officer in the dairy industry in 1993 after doing a degree in Chemical Engineering. I really wanted to work in an industry that is the backbone of industry in New Zealand. After working for a dairy cooperative for 5 years I decided to move into process engineering and project management as a contractor. This evolved into the founding of Techo Ltd as a vehicle to deliver the best turnkey dairy projects for clients.

As the Managing Director of Techo Ltd, I am responsible for the overall direction of the company. Often I will become involved in engineering projects as this is my passion.

Outside of work I love to fish, dive and snow ski as well as spend as much time as possible with my young family. As a family we love to travel and explore new places.

Warren Boyes


BE (Chem Proc.)

I'm a Process Engineer and Project Engineer and one of the Leaders at Techo Ltd. I received my honours degree in Chemical and Process Engineering from the University of Canterbury back in early 1999. I joined Techo Ltd in 2002 after several process optimisation, product development and operations roles within Fonterra and one of its precursors, Anchor Products.

What I love about Techo is our focus on quality engineering and quality projects and, with our wide array of skills, no two days are the same. We are small enough to react and tailor solutions but large enough to deliver a quality product repeatedly. No cookie cutters solutions here, we take time to develop a relationship and understand our client's needs before offering the "most correct solution".

I live in Auckland, with my wife, three daughters and (female) dog. Sucker for punishment... When I'm in Auckland there is always a netball game, hockey game, ballet show, gymnastics competition, swimming competition, or the myriad of trainings all over the city to ferry kids to or watch. In between time I enjoy family camping in the summer time and snow skiing in the winter. For quiet time I take the dog out for a run most mornings. I serve on the committee of the Eastern Suburbs Gymnastics Club and head up the subcommittee for building a new gym.

David Lacey

General Manager
HSEQ Manager


I have worked in various roles across a variety of industries in New Zealand, the U.K. and Japan. This has included designing the fire protection systems for the Aotea Centre in Auckland and later Canary Wharf in London, working as a site manager suring the construction of a factory being built for Toyota Motors in the UK, designing fire protection systems and carrying out overseas project management in Nagoya, Japan and more recently selling enterprise level software as a service solutions to large corporates and government organisations in New Zealand.

My role at Techo is to ensure we have the systems and procedures in place required to ensure all projects are delivered to a standard that exceeds client expectations. Managing the Health & Safety, Quality and Environmental aspects of how we work are also critical.

Outside of work I mountain bike regularly and ride my dirt bike most weekends.

Chris Hilton


NZCE (Mechanical)

I completed my NZCE Mechanical / with control systems in the 80's. I then spent several years with Nu-Con building and commissioning projects around the world, including 1 year in the USA. I specialised in automation projects from the mid 90's to mid 00's, working on Dryer 5 Te Rapa (Fonterra), Dryer 2 Clandyboye (Fonterra), Lichfield Whey plant (Fonterra) and Heinz Watties kitchens to name a few. During this time I owned a Super Critical CO2 plant and worked on various research projects. In 2007 I became a partner in Techo Ltd.

During my time at Techo we have completed many challenging projects. I value having a complementary range of skilled people within the Techo team who are capable of solving every challenge thrown at them. I especially value the relationships we have fostered with suppliers and contractors throughout the country, the result of which means we can call on many highly qualified and proficient people and companies, to support us with the projects we are working on. I have had the pleasure of working in depth on a number of Fonterra sites and continue to enjoy commissioning projects with Fonterra's site teams.

My wife and I have a young daughter, two teenage boys who are attending Hamilton Boys High and two adult daughters, all of whom I try to give as much time as possible. I love watching the boys rugby and athletics and we enjoy time at the beach over summer. I also like to ride my dirt bike when possible.

Ryan Mitchell

Construction Manager

Fabrication Trade Cert

My role as construction manager is to oversee the construction and installation works on various projects. This role usually requires being based on-site for the duration of projects and includes management of subcontractors and suppliers, and working closely with clients to deliver a safe, high quality project. Prior to working with Techo I completed my trade as a Fabricator Welder which led to working on a large number of dairy, food and beverage and industrial projects around New Zealand.

When I'm not working I enjoy spending time with my wife and two young girls and riding trail bikes.


Zeb Cookson


Dairy Dip.

Prior to joining Techo I had 20 years of dairy industry experience with Fonterra and legacy companies in various manufacturing and process technical support roles. My areas of expertise include milk treatment, milk powder, casein, membrane and CIP processes.

I am focused on bringing resources together to deliver top quality solutions that our clients can be proud of and that are operator friendly.

When I'm not working I enjoy off road motorcycling, mountain biking and surfing in my spare time.

Paul Graham

Project Engineer

Electrical Trade Cert (maintained)

I specialise in project design, equipment procurement, and project management and regularly work across the full scope of a project, from scoping, costing and conceptual design works, through to budget development, detailed designs and project implementation and development.

Prior to coming to Techo I worked on industrial plant process control and automation in the Bay of Plenty area. I have worked at most Fonterra sites over the years, including one year spent at the Reporoa plant (which processes enough milk a day to make more than eight million flat whites!!) and another spent at the Hautapu plant, the plant responsible for making "pink gold" a.k.a lactoferrin, which is used in yoghurts, infant formula and health products.

I was born and bred in Tauranga and am now based in Papamoa. I have two teenage sons, both of whom attend Mount Maunganui College. We are all keen on mountain biking which is handy seeing as we live in such close proximity to some of the region's best mountain biking trails. I am also a keen motorbike rider and I split my riding time between my trials bike and my adventure bike.
