Founded in 2012, Guest Hambleton was created to provide clear and practical advice to business clients, backed by strong experience of the commercial legal sphere.

As lawyers, we pride ourselves on our deep and detailed knowledge of the legal worlds we operate in. As people, we’re proud of being approachable and straight up. Combining the two means our clients always know where they stand.

The law is ever-changing. It’s not enough to perform the same kind of legal work over and over again. Understanding this – and serving our clients best – means responding to change with new ideas and new ways of working. That’s why we’re dedicated to being open with our clients, to keeping them abreast of legal realities, and bring their business ambitions to life.

Whether we are solving property problems, advising clients on joint ventures or RMA issues, our approach is the same – cutting through the complexity, and finding the best possible way forward, every single time.

Sam Guest - Director

Sam GuestLL.B / BCom


Dunedin has always been my home, growing up here and graduating from the University of Otago in 2004.

After practising locally for many years, I made the decision to establish a new firm in 2012. I wanted a legal practice that reflected my own values, a smaller firm where I could take real ownership of my clients' legal needs. It was one of the most exciting moments of my professional life.

Having gained a strong understanding of New Zealand's business and property law realms, as well as fisheries, dispute resolution and many other areas, it was time to take the services we provided to the next level and I approached Henry to join me in business. I knew from working with Henry previously that his skills would complement my own, and we would make an extremely effective team.

Together we lead a firm that's focused squarely on our clients and their legal issues. We're there for them, and they know it. I believe that this kind of loyalty breeds real trust, and that's the difference. Our clients know that our door is open, and we'll find the answer – every time.

Henry Hambleton - director

Henry HambletonLL.B / BCom


Having grown up on the Taieri Plains, I graduated from the University of Otago with a law and commerce degree in 2010.

The next 9 years were spent working in another commercial law firm in Dunedin. These years involved advising on a broad range of commercial transactions such as the sale and purchase of commercial, rural and residential properties, commercial and rural leases, the acquisition and sale of businesses and capital raises. Other advisory work included advising on commercial contracts such as manufacturing agreements and advising on asset structuring (i.e. shareholders’ agreements and Trusts etc).

Having worked with Sam previously and then having seen his firm grow and develop, the decision to join him at the firm in 2020 was easily made. I now look forward to working with Sam and the rest of the team at Guest Hambleton and providing pragmatic commercial legal advice to our clients..

Rob Pile - Lawyer

Rob PileLL.B


After graduating from the University of Otago in 2013, I was admitted to the bar and began my career in Christchurch. The post-earthquake environment in Christchurch at that time was fertile legal ground and provided me with the perfect platform to gain valuable experience on a wide range of private client and commercial matters.

In 2016 I relocated home to Dunedin to build on my existing network of relationships formed during my secondary school and university years. Since returning to Dunedin, I have seen a need for accessible, local lawyers who provide practical, clear advice that clients understand. That is why I am pleased to join Guest Hambleton, a firm known for delivering quality results and not sugar coating their approach.

Sam, Henry and I work closely together and advise on a wide range of legal matters. In particular, I have a special interest in commercial, rural and residential property matters, as well as asset protection / planning.

Alistair Paterson -

Alistair PatersonLL.B, Commissioner for Oaths (Aust)

Dunedin born and bred, educated at Otago Boys, I graduated Otago University and was admitted to the High Court in 1974. While attending University I was employed by Trustees Executors and that lead to developing an interest in estate and trust law. Later in partnership with Jack Lemon and Graham Duff undertaking conveyancing, commercial and Local Authority law (Otago Harbour Board) as well as general practice.

For the last 40+ years as a sole practitioner specialising in conveyancing, estate, commercial and trust law, I have seen a lot of law.

I have always enjoyed the personal inter relationships with clients and have noticed latterly I was acting for a number of the second generation of my original clients. I am now semi retired and I am keen to ensure my clients continue to receive the standard of care I strove for during practise.

I consider that I have always provided effective and timely legal services and now with a group of extremely competent and capable younger lawyers at Guest Hambleton I am anxious for my clients to receive effective, proactive and timely results.

I will be pleased to discuss your ongoing representation and act as a conduit for introductions to the new firm.

Born and raised in Nelson, I completed a double degree in Law and Physical Education from the University of Otago, graduating in 2017.

I then started my legal career with a local Southland firm based in Invercargill, gaining wide experience in private client and commercial matters.

Late 2020, I relocated back to Dunedin to join Guest Hambleton where I will be working alongside Henry and Sam on a range of commercial and property law matters. I look forward to meeting clients of the firm and providing them with clear practical legal advice.

Outside of work I enjoy spending my time in the outdoors and exploring the south with friends and family.
