Formed in the mid 1990s HMA (Hall McMaster & Associates Limited) developed around the work of Ken McMaster. Ken has a long history of work in the stopping violence, sex offenders, alcohol and drug abuse, and criminal justice areas. Although initially based in Canterbury, New Zealand, HMA has expanded to include trainers, programme developers, supervisors, and writers in the area of human service work in a range of other localities. This includes staff based in Auckland, Palmerston North, Wellington and Christchurch. Much of our work occurs in the areas of consultation in criminal justice work, social work with men, family violence prevention training programmes, child protection, the interviewing of children experiencing trauma, abuse issues, and psychological assessment and therapy. HMA provides group programme design and training for trainers, group facilitation skills training, social services supervision, and training in motivational interviewing. HMA also applies its expertise to the design and delivery of training in other fields. Research in areas related to our practice is important to us, and we both write and publish social service books.
