Our core purpose is to empower the energy future for New Zealand – a future that delivers a net-zero carbon economy and a reliable and secure electricity system.

Mechanical and Civil Engineers at Transpower work on exciting substation and transmission line projects essential to powering lives and communities across the country.  Watch some of our people talk about what they do here: Mechanical / Civil Engineer

Summer Interns are key to ensuring we have a pipeline of potential graduate engineers with the experience, skills, and behaviours needed to succeed in graduate roles throughout the business after completing their studies. 

About the opportunity

Starting mid-November through to mid-February each year, you’ll join Transpower as a paid Summer Intern (earning a living wage). From day one, you’ll be given meaningful work and supported by a collaborative, professional, and knowledgeable team. You’ll gain a first-hand understanding of what it’s like to work with us, and where Transpower as New Zealand’s owner and operator of the National Grid, is going in the future.

You’ll benefit from support, coaching, and mentoring from our dedicated Early Careers Programme Lead, second-year Summer Interns, and a buddy from our extensive Young Professionals community. Together, they’ll help you settle in quickly and build valuable relationships across the business.

In our Head office Waikoukou in Wellington, you’ll have a phenomenal opportunity to experience Transpower, while also completing some of the Engineering hours required to graduate.  If you’re joining us from another region, previous interns have successfully arranged group accommodation or stayed at Victoria University’s student halls, which are a short walk from our office.

Building positive relationships, learning on the job, and delivering outstanding work will give you a real advantage if you choose to apply for our Transmission Lines Graduate Programme or other specialist positions shaping the future of Electricity Transmission.

To be considered for our Summer Internship Programme, your CV and cover letter will demonstrate that you:

• Are working towards a Bachelor of Engineering (Civil or Mechanical) with a cumulative GPA of 5.5 or higher (please have your transcript ready to upload)
• Have well-developed written and verbal communication skills
• Have a genuine interest working at Transpower, and how electricity will enable the energy future
• Are studying at a New Zealand university and are a citizen, resident, or hold full eligibility to work in New Zealand

At a conversational interview, we’ll be looking to further explore your critical thinking, curiosity, and the ability to work well with others.
