This paper reports on a research programme that has investigated the migration experiences of highly skilled professional and business migrants to New Zealand. Over a four-year period, five separate studies have been conducted on the stages in the process of migration. The paper sets out a model of the stages of the migration process and the data and analysis which it has guided. Of particular interest are the information sources available to potential migrants and employers, the cultural sensitivity of settlement processes and the migrants' subsequent ease of access to the labour market. The paper analyses information flows available to migrants at crucial phases in the migration process based on a stages model of the migration process. The model indicates some of the critical steps, interactions, and decisions in the migration process from the individual's point of view. Crucial information gaps are identified and implications are drawn for actors involved at the different stages.
