The chapter reviews developments in New Zealand's immigration policy between 2003, when the innovative "expression of interest" (or "by invitation") selection system for skilled migrants was introduced. This system has been subsequently adoped by Australia (2012) and Canada (2015) with amendments to suit federal systems of governance and a variety of sub-national (State/Province) selection systems. The review traces the impact this scheme had on skilled migrant selection between 2003 and 2010. Other developments in immigration policy affecting those seeking residence in New Zealand under the family sponsorship and international categories of entry are also reviewed briefly. A companion chapter by Bedford, Callister and Didham, "Arrivals, departures and net migration, 2001/02-2008/09" reviews the comprehensive data Statistics New Zealand collects on all peoiple crossing the international border (pp. 50-103).
