ELEVATING ENERGY
New Zealand has one of the world’s most competitive energy markets, with high churn and plenty of players offering near-identical services. To stand out, Mercury needed more than another utility app that just showed usage, bills, and payments. In fact, Mercury didn’t yet have an app at all — this was their first step into the space. The challenge was to create something that not only delivered the expected features but also embodied the brand’s ambition of “making energy wonderful.”
My role was to help translate that ambition into a mobile experience. Through competitor analysis and user testing, we saw where energy apps typically fell flat: confusing navigation, bland interfaces, and little that felt genuinely rewarding. From the ground up, I designed an app that made the basics simple — checking usage, paying bills, updating details — while also weaving in ways to surprise and delight.
The biggest differentiator was finding ways for customers to use their own energy — whether brain energy, physical energy, or everyday choices — to earn Mercury Dollars. Walking challenges encouraged physical activity, while quizzes gave customers a fun way to put their brain energy to work. Those Mercury Dollars could then be used to reduce their bill, convert to Airpoints, or even donated. By tying the brand’s vision directly into the product, the app became more than a transactional tool; it was a way for customers to feel recognised and rewarded.
The outcome was Mercury’s first app — an experience that felt clear, engaging, and distinctly on-brand. It gave customers practical control over their energy while creating meaningful moments of value that brought the brand ambition to life, helping Mercury stand out in a crowded, competitive market with plenty of room to grow.
