Our Philosophy

Kotahitanga is a psychological service where we provide a range of tailored psychological therapies to meet clients’ individual needs, and our aim is to provide a supportive and safe environment for our clients to work on what they wish to achieve, and to enhance or rebuild connections with their loved ones.

In our service we work with the philosophy where we believe that mental health is impacted by all areas of our lives. Wellbeing is about being healthy physically, mentally, spiritually, and having loving and supportive family relationships.
We work with people from all ethnicities, faiths, sexual orientations, ages, and disabilities.
