The 2002 Study
The 2002 New Zealand Election Study was conducted by telephone and mail questionnaire. The study includes Module 2 of the Comparative Study of Electoral Systems (CSES). Post-election, questionnaires were sent by post to arrive on Monday July 29, followed by a reminder postcard ten days later, with a second questionnaire ten days after that to non-respondents. From mid-October until the end of November 15 minute telephone interviews were conducted with as non-respondents for whom telephone numbers could be found. Not all questions could be included given the interview length constraint. The overall response rate from the citizen samples selected was 60.8 per cent. However, some sub-samples were taken from previous samples and therefore subject to attrition. The 2002 NZES has five major components.

1. A 'New General Sample'.
This was randomly selected from the electoral rolls, proportionately from each of the 62 General parliamentary electorates and conducted immediately post-election as detailed above. For the new sample the postal response rate was 44.6 per cent (N=1338), with the telephone interview adding another 8 per cent (N=248), making a combined response rate of 52.2 per cent (N=1586).

2. Election to Election Panels.
Administered post-election as explained above, these samples contain respondents from the 1996 and 1999 NZES (Vowles, Aimer, Banducci and Karp 1998; Vowles, Aimer, Karp, Banducci, Miller and Sullivan 2002)). The 1996 panel had an N of 533 and 1999, 537. Of all panel respondents 1040 completed the postal questionnaire, and 120 were followed up by phone. Respondents within each panel were subject to different levels of response rate attrition, but no significant or obvious non-response bias was apparent.

3. The Campaign Pre-election Sample and Pre-Post Panel.
The pre-election campaign N was 3590, with a target of 100 interviews for the 36 days immediately before the election. The response rate was 34 per cent. This was a random national sample from households with telephones conducted for the NZES by ACNielsen (N.Z.) Limited. Respondents were randomly selected from within households. Campaign respondents were also asked to participate post-election and the 3190 who agreed to do so were mailed the post-election questionnaire. Of these, 2008 responded again by post, 514 by phone, making for a response rate of 79 per cent of those who had agreed to participate. Merging the pre- and post data by respondent thus constitutes the pre-post panel. The post-election mailing and interview schedule followed that detailed above. For further details, please review the full description of our methodology.

4. Maori Election Study.
The Maori Election Study is an over-sample from the Maori electoral rolls (N=500). The response rate was 33.3 per cent, of which 27 per cent came from the mail questionnaire and the remainder by telephone. The mailing and interview schedule followed that explained above.

5. The Candidate Study.
Over the same period as the voter surveys, although excluding the telephone top-up, mail questionnaires were sent out to all candidates standing for parties with seats in the House, or likely to gain any. The candidate survey provides data on the respondents' background, recruitment and selection, role as an MP (if relevant), and attitudes. Questions on issues and policies replicated those in the voter surveys, enabling comparison between the attitudes and behaviour of voters and candidates.
