Meet the Team

Christina Matthews

Senior Executive
I'm an ORL trainee; originally from Auckland but over the years I have worked in Northland, Auckland regions, Christchurch and Waikato.

As part of the STONZ Executive, I welcome contact from all members and look forward to representing RMOs across NZ. I have previously sat on RACSTA and the ORL board as the New Zealand trainee representative.

I joined STONZ when I was a non-trainee, as I believe we have a good balance between adequate and quality training, for our junior doctors.


Jordan Tewhaiti-Smith

Senior Executive

Kia ora! I’m Jordan, currently an O&G Training Registrar based at Christchurch Women’s Hospital. I grew up in the Wairarapa but have huge connections to the South Island. Ko Ngai Tahu, Ngati Kahungunu me Ngai Puhi oku iwi. I have experience working in large tertiary hospitals, and smaller provincial hospitals as well.

STONZ reflects my goals for training now and for the future, and I also feel that STONZ has RMOs and patients at the centre of our work. In a time where the public health sector is changing constantly, and not always for the better, I hope to be able to facilitate balanced communication with the RMO workforce coming through (including TIs) and support them in joining a union that works for them and fights for the rights of RMOs to be trained, competent practitioners. I am proud to be part of this union which values people and training at its core.


Richard Storey

Senior Executive

Richard Storey is a recently qualified orthopaedic surgeon. His training journey has taken him from Dunedin, to Christchurch, Wellington, Waikato and now is back in Christchurch before starting his spine fellowship in Dublin.

He has had an engaging and rewarding experience over his 16 years of training and has balanced the demands of orthopaedic training with sports, research, union and family time. Particularly engaged in making a positive difference for his colleagues and therefore patients he has worked hard to find ways to make a positive impact during an everchanging training and working environment in Te Whatu Ora.


Emma Littlehales

Senior Executive

I’m a plastics trainee. Originally a UK graduate, living in NZ since 2016 I’ve now made my home here. I’m a member of the RACS Prevocational and Skills Education Committee, representing surgical non-training registrars. I got involved in STONZ because I worked in a system in the UK where juniors worked a 70-hour week to get the required experience for elective surgery but were only paid for 48.

I want to ensure NZ trainees get the required experience to become consultants in a safe way, whilst still being recognised and compensated for the hard work they do. I’m advocating for safe and evidence-based rosters, which allow for enough training time to develop safe Consultants. I also want to give a voice to non-training registrars, who are less protected than their trainee counterparts, and do a large amount of the day-to-day work in the hospital.


Alastair Hercus

Junior Executive
Alastair is an Anaesthetic trainee in the Auckland region who has been part of the STONZ Executive since 2022.

He is originally from Christchurch where he began his career and maintains strong ties to the region.

Alastair believes that STONZ best represents the needs of RMO’s through promoting safe work environments and fostering training. Fair renumeration and maintaining adequate RMO training are of particular interest to him. Collaboration on these issues is paramount, and Alastair looks forward to continuing STONZ connection with the various stakeholders to ensure these areas, among others, are addressed.


Bri Northey

Junior Executive
Kia ora!

I’m Bri, currently working at Counties Manukau as a Obstetrics and Gynaecology trainee. I grew up in Te Tai Tokerau in Whangarei and whakapapa to Ngāti Tukorehe in Otaki. 

I had three years of experience as a House Officer, then as a Senior House Officer at Tauranga Hospital prior to stepping up to a Registrar and feel I have a good grasp of the issues RMOs face. I look forward to talking to Registrars, House Officers and Trainee Interns alike. STONZ is run by RMOs and I believe, has RMOs best interests at heart. 


Chantelle Petterson

Medical School Representative
Currently a 5th year medical student (Christchurch Campus, Otago University). Prior to medical school, I was a proud STONZ member while working as an RMO in the Maxillofacial units in Christchurch and Waikato. I was privileged to be the delegate representative in 2022 and have recently moved into the medical school rep position. 

As the medical school rep, I am a link between the TI delegates reporting to the STONZ Exec as they pave the way for the next generation of junior doctors. I’m also passionate about supporting the cohort of current and future dental graduates who take up RMO positions. It’s an honour to be part of the team!

Brad Atkinson

Delegate Representative

Hi, I’m Brad, a PGY4 Non-Training Orthopaedic Registrar based in Whangarei Hospital that will be in the role of Delegate Representative for 2024. I chose to join STONZ as a Trainee Intern based on my career plans and the healthcare values that I wanted to uphold. After facing some contract issues early in my career and initially being unsure where to go for support, I found myself stepping into the role of STONZ delegate toward the end of PGY1 in Invercargill. 

Being a delegate is a very rewarding role in which colleagues come to you with various issues looking for advice and/or help to resolve specific issues. It’s also very rewarding being the “feet on the ground” that identifies some of the wider issues RMO’s are facing and raising these with the support team in a way that they can be addressed early. 

In 2024, I have stepped into the role of Delegate Representative alongside Dale Andrew. Together our role is to support delegates and find ways to develop the delegate role. Our plans for the year include regular delegate check-ins, Zoom catchups, education sessions and surveys. We are especially keen to hear from delegates who are having issues in the role or have ideas on how the role can be improved.

Dale Andrew

Delegate Representative

Hi everyone, I’m Dale and one of the Delegate Representatives for STONZ. I am currently an ORL Trainee based in Auckland, working part-time while undertaking my masters. I have been a member of STONZ since we first began as a union and have been increasingly involved since that time. 

I am passionate about our union and proud of the progress we have been able to achieve in our relatively short existence. I hope to contribute to this ongoing progress in whatever way I can.

The delegate representative role is essentially a go-between for the delegates spread out over the country so they have a regular point of contact, and person who can further their thoughts to the STONZ executive. We are involved in on-boarding new delegates, regular catchups to ensure we identify issues or concerns as soon as we can, and further disseminating any information as needed. I look forward to meeting you in the near future, don’t hesitate to reach out if needed.

Anika Radojkovich

Project Rep - Non-Training

I'm a non-SET surgical registrar who has dabbled in plastics, general surgery and orthopaedics. I spent my early years as a doctor in the Auckland region and have recently moved to Hutt Valley.

I joined STONZ because I believe their work is key in protecting and improving conditions for doctors. I am passionate about creating a safe working environment while still enabling us to get the most out of our time and training - which ultimately gives our patients the best result.

As the new non-training registrar representative my role is to advocate for those in the gap between House Officer supervision and the formal college progression. STONZ wants to improve the experience, training and protection of non-training registrars so we will be working on projects to create change in this area and capture information to communicate the experiences and difficulties for this group.

If you have any questions, concerns or experiences you want to share feel free to get in touch!

Maria Nonis

Project Rep - House Officer

Kia ora! I’m Maria, House Officer currently working in the Emergency Department at Christchurch Hospital and have recently taken up the position of the House Officer Projects Representative for STONZ.


I grew up in Christchurch and headed south for medical school in Dunedin. I love all things project related, including gardening, baking and embroidery.

I joined STONZ due to their strong work ethic and advocacy to improve conditions for doctors and patients. I am passionate about researching and evaluating current working conditions and how we can use our collective experiences to make positive change and improvements. 

Feel free to get in touch or say hello – I am always open to hearing any ideas, questions, or issues.

After completing his final exams and fellowship in orthopaedics, Earle stepped down from the STONZ Executive in August 2023.
