Aucklanders and false alarms

The Herald reports:

More than a quarter of all fire call-outs in the past financial year were false alarms, at a cost to taxpayers of up to $25 million.

Figures released to the Herald under the Official Information Act show of the 73,512 jobs the Fire Service attended in the year to June, firefighters turned back from 20,373.

The majority of false alarms – 41 per cent – came from the Auckland region, where up to 74 per cent of all calls to central city stations turned out to be false alarms.

The false alarm rate in Auckland appears to be two to three times higher than the rest of NZ. Any theories on why?
