Until 30 or so years ago, it was customary for 85 to 90 per cent of those New Zealanders eligible to vote in general elections to do so. From that standpoint, the worry aroused by that figure sliding to 68.8 per cent on Saturday has an obvious validity.
In sum, a million eligible people did not bother to vote. Yet it would be wise to keep this in perspective. The long-term decline in voting, especially by young adults, is far from restricted to this country. Add in some peculiarities associated with Saturday's poll and the turnout becomes more explicable.
Probably the most notable of these is that many saw the result as a foregone conclusion.
It is telling that the previous lowest turnout occurred in 2002. Just 72.5 per cent of those eligible voted in a contest that pitted a high-flying Helen Clark against Bill English and a struggling National Party. The similarity with an unconvincing Phil Goff confronting John Key is readily apparent.
It did not help, either, that while Labour advanced new policies, such as a tax on capital gains, and National had the contentious part-sale of state assets on its programme, these did not spark fierce debate.
