Dianne thrives on helping others, problem-solving and thinking outside the square.

With a rich and diverse background in business management, sales, marketing, and customer service, she brings a wealth of knowledge, and a broad skill set to real estate. Having worked across a range of sectors, including finance, education, health and disability, business/retail, and hospitality—this experience adds real value to the service she provides.

Dianne has built a strong reputation as a salesperson who goes above and beyond for her clients. Her focus is always on delivering an exceptional and personalised experience throughout every step of the property journey. Understanding that no two clients or properties are the same, Dianne tailors each experience to suit the individual needs of her clients.

Known for her enthusiasm, professionalism, and down-to-earth nature, Dianne operates with honesty, integrity, and a genuine commitment to putting her clients first. She keeps you fully informed throughout the process and works tirelessly to achieve the best possible result. With strong negotiation skills and a “client-first” mindset, Dianne’s ultimate goal is your satisfaction and success.

When she’s not helping clients, Dianne enjoys the Northland lifestyle—walking her dog, fishing, participating in the community and spending quality time with family and friends.

Thinking of buying or selling? Get in touch—I’d love to help you with your real estate journey.
