Upon completing her graduation, she proceeded with post graduate studies in the area of dental implants. Juliane has been practicing dentistry for close to 20 years, she  worked and owned her own dental practice in Brazil for 10 years before the beauty of New Zealand caught her eye on a visit to our shores and she relocated here permanently.

Juliane has been working with us at Marina Dentists since we opened the first clinic at Half Moon Bay and has a strong focus in general, cosmetic dentistry and implants.

Juliane keeps her skills and practice at the highest level by regularly attending courses and conferences,  and having completed training in facial aesthetics means Juliane is now able to offer Dysport and facial fillers treatment here at Marina Dentists.

Dr Fiona van Heerden


BDS Dental Surgeon


Fiona was born in the mainland and brought up on the east coast of the North Island. She studied at the University of Otago and was awarded multiple academic prizes. As one of the top students in her year, Fiona secured a position as a Dental House Surgeon at Canterbury Health. The opportunity to work as a dental house surgeon provided her with valuable experience with surgical extractions, including wisdom teeth removal and working with medically compromised patients.

Fiona then settled into private practice, moving to Auckland in 1997. Fiona became one of the first dentists in New Zealand to use CADCAM systems for providing dental restorations. These systems helps us to provide durable restorations while minimising patients’ wait times and the amount of tooth tissue which we need to remove.

Dr Sanchit Bhatia

BDS Dental Surgeon


Sanchit works at both our Half Moon Bay and Pine Harbour clinics as a dentist.  In 2002, Sanchit immigrated with his family to New Zealand and grew up in East Auckland. Having developed a passion for health care, he moved to Otago and pursued Human Nutrition before completing his BDS from the Faculty of Dentistry at The University of Otago, graduating with high endorsements.

Sanchit is enthusiastic, warm and passionate about providing the best care for all his patients and is a great support to all the co-workers in the clinic. Having a philosophy of providing personalised care which considers each patient’s individual lifestyles means Sanchit is comprehensive in his approach and believes it is crucial to understand his patients’ wants and needs before providing dental treatment. He is part of the New Zealand Dental Association, Auckland Dental Association, New Zealand Academy of Cosmetic Dentistry, and Professional Development and Mentorship programmes.

His love for travel and cross-cultural immersion allows him to connect with people of all ages and diverse backgrounds, making each patient feel welcome and comfortable, from children to anxious patients. While he enjoys all fields of dentistry, Sanchit has developed a special interest in urgent, restorative, minimally invasive and preventive dentistry.
