An advertisement that poked fun at Auckland Mayor Len Brown's extramarital affair has been cleared by the advertising watchdog as humorous and satirical.
A complaint to the Advertising Standards Authority (ASA) said the direct email advertisement for Naked Bus, which made reference to Mr Brown's affair with former mistress Bevan Chuang, was "in poor taste".
The ad offered a discount on mobile website bookings, saying: "Unless you're Len Brown, you'll probably agree that using out new mobile website to book cheap fares is a more useful (and appropriate) use for your mobile phone."
Mr Brown's council-provided mobile bill was investigated as part of an independent probe into his expenses.
It found his bill over the review period was $4538.50, of which the mayor reimbursed $265, and that Mr Brown used the phone for 1375 calls and texts with Ms Chuang - about 10 per cent of the total.
