National DBT Service

Te Whare Mahana offers New Zealand’s only national residential Dialectical Behaviour Therapy (DBT) programme. Situated in Golden Bay, Nelson Tasman, this internationally renowned programme is for people experiencing frequent high levels of distress and have had little success from hospital and community treatments.

Dialectical Behaviour Therapy is an intensive behavioural treatment approach, helping people work through complex histories and Post Traumatic Stress Disorder, and learn new skills for managing relationships and coping with distress. American psychologist Marsha M. Linehan developed the well-established treatment model as a better way of treating people with Borderline Personality Disorder and chronic self-harm/suicidal behaviours. DBT is now routinely used to treat a wide range of different and co-occurring mental health problems, including anxiety and depression.

DBT emphasises the learning and refinement of skills to help regulate emotions, change thinking patterns associated with problems in daily living and reduce misery and distress. DBT incorporates the acquisition of skills to assist residents in improving interpersonal effectiveness and their quality of life.

 “Before coming to us, our DBT residents’ multiple suicide attempts and frequent severe self-harming episodes have really challenged DHB outpatient mental health services. When referring, clinicians often describe our residents as being ‘on a trajectory to death’. They have exhausted all local treatment options but are wanting to live – that’s what we give our residents, their lives, their futures.” Shelley Harvill, DBT clinical manager.

Originating from the Mississippi delta Dr. Shelley Harvill is highly experienced at group facilitation within natural environments and amongst diverse cultures. After helping to build and direct a community integration programme for people living with serious mental illness, Shelley obtained a Doctorate of Psychology from Forest Institute of Professional Psychology, Missouri. Seeking to learn about nationalised healthcare systems and to continue her interest in the schizophrenia recovery field and mindfulness-based approaches, Shelley completed post grad work in Nova Scotia Canada. Being an integration of western and eastern psychological philosophies and backed by strong research, DBT became one of Shelley’s preferred therapeutic models to effectively treat people with complex needs. She has completed multiple DBT intensive trainings, including Radically Open DBT, which is aimed at people with over-control issues as found in treatment resistant depression and eating disorders.

"With whakapapa back to England, Scotland, and Denmark, Nick is a fifth-generation pākeha New Zealander. Raised in a strong family and extended family environment in Tāmaki Makaurau / Auckland and having also spent formative time in Ōtepoti / Dunedin and Te Whanganui-a-Tara / Wellington, Nick moved to Mōhua / Golden Bay in early 2021 to live in a more sustainable and connected way. Nick completed his Doctorate of Clinical Psychology at Massey University, investigating the question of how psychologists can assist individuals experiencing distress due to bigger-than-self issues in society and the biosphere. This inquiry informed a clinical philosophy grounded in embodied embedded mindfulness practice, which naturally fits with the focus of DBT as a treatment approach. In his spare time, Nick enjoys tramping, DJing, field hockey, and is an avid Black Caps fan."
