Opinion polling has been commissioned throughout the duration of the 46th New Zealand Parliament and in the leadup to the 2002 election by various organisations. The main four are Television New Zealand, TV3, The New Zealand Herald and Roy Morgan Research. The sample size, margin of error and confidence interval of each poll varies by organisation and date.

Party vote and key events
Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between survey firms.
