Janet Marshall doesn’t just talk about giving back – she lives it. Director of Commercial at Colliers on the North Shore, Janet is one of Auckland’s leading figures in commercial real estate.
But her story doesn’t start there – it begins thousands of kilometres away, with roots that have shaped not only her career but also her deep sense of gratitude and social responsibility.
Born in Singapore and adopted as a baby, Janet was raised in the UK, where she enjoyed what she describes as “a wonderful upbringing and excellent education”. She later emigrated to New Zealand with her husband and two children – a move that would mark the start of a new chapter both professionally and personally.
“I often reflect that if I hadn’t been adopted, I could be living a completely different life – speaking another language, in another country,” Janet says. “That sense of perspective has stayed with me. It drives my desire to give back whenever I can.”
Today, Janet’s commitment to service is clear. She sits on two business association boards, volunteers as a business mentor, and has recently been sworn in as a Justice of the Peace. She is also a passionate supporter of breast cancer research – a cause made deeply personal after the loss of a close family member. As a patron of the Breast Cancer Foundation NZ, Janet helps organise community fundraisers like the recent Super Pink Breakfast in Takapuna, which raised more than $3,000.
“It’s not just about doing good – studies show that giving back actually makes us feel better too,” adds Janet. “It gives you a real sense of purpose and joy.”
I love finding the win-win for everyone. The tougher the deal, the more satisfying the result.
Janet’s path into commercial real estate wasn’t typical. She joined Colliers in an admin role in 2002, with no sales experience. Encouraged by management, she took a leap into brokering – and ended up being awarded Rookie of the Year!
“I didn’t see myself as a salesperson, but once I started, I loved the challenge of solving problems for clients,” she says. “Commercial property is more business-driven, complex, and financially oriented than residential. It’s important to have a deep understanding of local markets, trends, rental rates and property values.
Janet’s consistent repeat business is a strong testament to her integrity and the trust she has earned from her clients.
Her rise has been impressive. In 2013, she was named Marketer of the Year, and by 2016, she had been appointed director at Colliers. In 2019, she was honoured with the Women in Property Award from the Property Council of New Zealand.
She describes herself as a “possibilitarian” – someone who always sees what could be. “That’s a real word!” she laughs. “I love finding the win-win for everyone. The tougher the deal, the more satisfying the result.”
Janet is passionate about mentoring and sharing her journey and successes within the commercial sector. “Believe in yourself and your unique strengths,” she advises. “Be authentic, stay curious, and never stop learning. There’s a place here for you.”
