Short bio

DETA Consulting is your leading optimisation and project delivery partner. We analyse the impact of our solutions on the client’s operation as a whole – we consider practicality, health and safety, business and environmental concerns. We ensure our analysis is “real” and that clients can make informed decisions about their projects. Together with our clients we deliver quality strategic results. We were born out of energy efficiency but have grown and evolved to deliver services across the wider engineering optimisation and sustainability spectrum from process optimisation, to water and wastewater reduction, through to carbon footprinting. We also have a dedicated project delivery team with expertise to provide as much support as you require from business case through to completion, or to adding value where required through the addition of a skilled resource to strengthen an existing delivery team.

Our team have a passion for improving performance – check out some of our success stories here.

Awards and Recognition

DETA has won a range of industry awards for our industrial productivity and project delivery work. Our client ANZCO Foods was awarded the 2016 EECA Energy Management award, in large part due to the energy management programme that we have managed for them since 2012. We are at the forefront of industrial energy technology having rolled out several New Zealand ‘First-in-Country’ projects in the refrigeration and energy generation space. These have led to two EECA Innovation Awards: in 2016 for the Hellers high temperature heat pump project, and in 2018 for the Hanmer Springs geothermal methane turbine generator project.
