About Simon

With more than 24 years of real estate experience and over $600 million in combined sales, Simon Siddells and Dianne Maxwell bring proven expertise, honest advice and energetic execution to every campaign. Working across Remuera, Parnell and the Double Grammar Zone through to Meadowbank, Orākei and the Eastern Bays, they understand that every property and every vendor’s circumstances are different. Rather than relying on a fixed formula, Simon and Dianne recommend the sales strategy best suited to the home, the market and the desired outcome. Their approach is personal and hands-on from the outset. They provide practical advice on where preparation will add value, coordinate trusted trades and presentation specialists, and ensure every property is positioned and marketed to connect with the widest possible audience. Simon’s experience across changing markets brings sound judgment to pricing, strategy and negotiation, while Dianne adds another valuable perspective, extensive buyer relationships and the ability to communicate in Mandarin. Together, they offer vendors greater availability, wider buyer reach and two agents who remain personally involved throughout the entire process. Known for their straightforward communication, Simon and Dianne provide honest buyer feedback, clear weekly reporting and considered advice at every stage. Their aim is simple: to reduce the stress of selling, create genuine competition and achieve the strongest possible result—whatever the market.

Great communication, knowledge and expertise!

Simon worked with us to sell our mum’s home. He managed the sale process really effectively, demonstrating a strong knowledge of the market and creative thinking finding buyers that may have not looked at it without his approach. He and Dianne were excellent and we got a good result.

Simon and Dianne were understanding of our family situation and made the sale low stress and easy

Simon and Dianne communicated honestly from the start and, in a difficult market, made the sale of our property happen. Their knowledge and ability to communicate the best way forward at each part of the process was great and despite us not being in the same city as the property we could trust their judgement fully. They made the negotiation with the purchaser work, despite numerous tricky demands, and Simon went out of his way to help fix the little things in order to get the purchase completed. Dianne's summaries were helpful and professional. Simon and Dianne worked well together as a team and the communication with us was clear. We would recommend them both to others.

Extremely knowledgeable & makes the whole experience as stress free as it can be.

We chose to work with Simon because we had engaged with him earlier, but decided not to sell at that time. We were impressed with his vast knowledge & experience and very personable manner, so it was a no brainer to reach out to him to sell our home, when the time came. Simon is great at setting realistic expectations, with solid backing for those. From initial meetings through to dealings post auction, Simon has been an absolute pleasure to work with. We are given clear and speedy feedback after each viewing and open home and importantly for us, it was Simon and his partner Dianne who ran those. We really felt everything was done to secure a sale and Simon, his partner and the entire Megan Jaffe Ray White team went above and beyond. In the lead up to the auction, we were given all the information we needed, which was very clear. The auctioneer was wonderful and I can happily say everything has been faultless, at every point. I would recommend Simon and his team without hesitation.

Great understanding of our needs

Simon was very professional at all times and conveyed the market well to us. He also has an appreciation of what sells a house and how to present it well to the market. He put us in touch with many tradespeople to be able to do this. He was always available and responsive for any questions we had. Our experience with the sale, and purchase of another property with Simon was as stress free as it could be and seamless.

Enthusiastic and Professional Agent

I engaged Simon to sell my mothers apartment following her death, and was consistently impressed with his enthusiasm and professionalism. Our initial meeting put me at ease that I had found an agent whom I could easily work with. Simon kept me well informed at all stages of the sale process and was always available to answer any questions I had. He worked hard to facilitate a sale result I was pleased with, in what at the time was a difficult real estate market. I would not hesitate to engage Simon’s service for future property sales.
