Many immigrants could be among those who failed to vote in this election, and those from North Asia or North America and migrants who "felt very settled" were less likely to vote, a Statistics New Zealand analyst told a population conference yesterday.
Voter turnout for the 2011 election was the lowest in percentage terms in 120 years, and although there are no figures out yet, a large percentage of non-voters may be migrants.
A survey done jointly by Statistics New Zealand and the Department of Labour in 2008 just after a campaign to get people on the electoral roll found only 88.4 per cent of immigrants were enrolled, compared with the New Zealand average of 95.3 per cent.
However, the number of those who actually turned up to vote could be significantly lower, it is believed. About a million enrolled voters did not vote in Saturday's election.
"Migrants from traditional source countries like the UK and Ireland were significantly more likely than those from other regions, including South Africa, North Asia and North America," said statistical analyst Dr Anne Henderson.
