Hydrologist/Water Resource Scientist


WGA NZ (Wallbridge Gilbert Aztec New Zealand) is a multi-disciplinary, award-winning engineering and science team with an ethos based on developing long-term collaborative client relationships, and delivering innovative, buildable and economical solutions. We have a great opportunity for a Hydrologist to join our established close-knit water group team of hydrologists, engineers, hydrogeologists, and numerical modellers. Though you would be joining a smaller team in New Zealand, you will also be supported by close to 500 staff from other offices across Australasia.

To be our successful candidate will have an appropriate tertiary degree in Hydrology or Environmental Sciences or engineering and ideally have at least intermediate experience in hydrology or environmental consulting. You will also be well networked and recognised as an community member in your specific water professional discipline areas.

WGA NZ has been based in New Zealand for over 5 years with a passionate team of dedicated scientists working on integrated water management projects including a focus on developing water security and resiliency solutions in response to the pressures of climate change. Our Water Group is working on exciting and high-profile water projects both here in New Zealand/Australia as well as internationally in North American, the Middle East and elsewhere in the developing world. 

Whilst WGA NZ currently has offices in Auckland, Hamilton, and Christchurch, at WGA, we are focused on ‘finding the right people’, and are open to your ideas about remote working and/or home office options across the country. Regardless of your location (in the office or remote), you will have the ability to work on projects nationally and internationally when the need arises.

Your day to day duties and responsibilities could include but are not limited to:

  • Providing specialist hydrology and environmental science advice across a variety of environmental, water supply, sustainable groundwater management, construction, and mining projects both locally and internationally

  • Assisting with the preparation of proposals

  • Designing and implementing complex water investigations including hydrological and environmental science support for Managed Aquifer Recharge (MAR) projects

  • Conducting field works including site assessments, flow site installations, and monitoring

  • Undertaking hydrological modelling and data analysis

  • Ability to work closely with your team members both in person and remotely

  • Preparing hydrological and environmental technical reports

  • Continue to help WGA develop new business opportunities through networking and business development activities

On top of the right qualifications and experience, to be successful in this role you will need to be able to demonstrate:

  • Well-developed field work skills

  • Excellent report writing

  • The ability to develop long term collaborative client and peer relationships built on respect, performance, honesty and trust

  • The ability to create innovative solutions which add real value and deliver quality outcomes

  • The desire to attract and develop new business as required

  • Experience with industry standard modelling software packages.

Please also note- suitably qualified professionals located in other major centres across New Zealand and Australia are still encouraged to apply.


The New Zealand based WGA team includes some of New Zealand’s most highly respected professionals in their field. You would have the opportunity to further your technical learning and the right candidate would also have potential for career progression within the organisation.

At WGA we offer our employees an open, supportive working environment which allows for autonomy, creativity and career growth potential. We enjoy a social and inclusive culture and value work/life balance, offering flexible working conditions to meet personal circumstances, along with a plethora of additional perks such as an employee assistance program, paid parental leave, ongoing paid learning opportunities and the ability to purchase additional annual leave (just to name a few).
