If it affects your public job, then it is a matter of public interest
The Post reports:
A person with a front row seat to Tory Whanau’s Wellington mayoral campaign has talked of her missing meetings after nights out drinking and of how volunteers had to police her alcohol intake. …
The campaign volunteer, who spoke anonymously to protect job prospects, said Whanau would frequently cancel morning events after nights out drinking.
Everyone knows this has carried on as Mayor.
Questions were raised in in May when Whanau missed a regional mayoral forum to discuss water reforms.
Her frequent absence at civic functions – including monthly citizenship ceremonies, in which the mayor welcomes new residents – had also been noted. Also in May, she pulled out of a Government House ceremony for young Duke of Edinburgh award winners.
On the same day, dignitaries were embarrassed when she was missing from a commemoration of the 1941 Battle of Crete.
The Mayor is paid a salary of $180,000 a year. Turning up is not an unreasonable expectation.
