Mayor Len Brown has gone to some lengths to promote his plan to make Auckland's municipal swimming pools free.
Having detected an "overwhelming sentiment" during the election campaign to replicate Manukau's free pools across the city, he pumped up the proposal by making it part of his "100 projects in 100 days" programme.
Never mind that critics said there was no public call for free pools beyond Manukau, and that people were simply responding as they would to any free offer. The Mayor ploughed ahead regardless and sought confirmation of his view through a report from international consultancy KPMG.
Unfortunately for Mr Brown, that report provides anything but solid backing. It puts the cost of free entry to the Auckland Council's 24 pools at just $5.5 million, even though it cost $6.7 million to provide this to Manukau's six pools when Mr Brown was mayor of that city.
This is completely contrary to suggestions that it would cost up to $50 million a year to provide such a service. The reason for the discrepancy is that, astoundingly, KPMG assumes free access would create an initial increase in use but that, in the long term, this would settle to around current levels, and that new revenue would be collected from spas, sauna, steam programmes, and retail sales.
