participated in this study. These people were first interviewed by telephone by Statistics New Zealand (SNZ) interviewers and subsequently agreed to participate in more extensive face-to-face interviews undertaken by National Research Bureau (NRB) staff. The work of the SNZ and NRB interviewers and other staff from these organisations involved in the survey in various ways is also acknowledged. In this regard, Jonathan Briggs, a SNZ mathematical statistician, and Andy Heinemann, the Director of NRB, deserve special mention. The support and assistance with critiquing early drafts of the manuscript that was provided by Department of Internal Affairs staff, namely John Markland, Margaret de Joux and Mike Osmond is also noted with gratitude. Rachel Volberg contributed to the design of the study and questionnaire. A number of other people contributed to the study by providing internal and external audit of the research design and data analysis. NRB staff undertook cognitive testing and piloting of the phase two questionnaire. Carol Garnett, Personal Assistant to the author, assisted with desktop publishing and editing. While the substantial contribution made by these people is acknowledged, editorial responsibility resides with the author alone. Published by
