Abstract: An overview of the model of nursing practice and nurse roles derived through a programme of nursing research in the context of the changing New Zealand health system. The emphasis is on the complementary nature of the practice of family nurses taking a generic integrative service delivery hub role and the practice of other nurses advancing in specialist roles. Nursing care is presented as a professional, collective practice of registered nurses spread across all health service sectors and employment settings. Nurse roles are differentiated according to the interplay of two factors influencing the extent of practice autonomy the nurses assume (educationally supported) in responding to health need. A diagram depicts the interrelationship of competency and scope for the inclusive three different career trajectories of nurses advancing in practice.

An apology from the journal editor with an explanation of the importance of the use of the term ?advancing? and not ?advanced? was published in the subsequent issue (Nursing Praxis in NZ,14(1)).
