Auckland Council's manager of environmental health Mervyn Chetty said the concert did not breach noise rules.
"The maximum level of noise measured at the mixing desk during the event was 103 decibels," he said.
"The permitted maximum noise level when measured at the mixing desk at the stadium is 107dB."
Of the 27 noise complaints received, four came from Mt Eden, five from Ponsonby, three from Freemans Bay, one each from Newton, Kingsland, Eden Terrace and St Lukes, and seven from Grey Lynn. Four were anonymous.
Mr Chetty said the noise level of the gig was similar to recent concerts, including the Foo Fighters (98-104dB), Eminem (101-105dB) and the Big Day Out (101-109dB).
The concert's publicist, Sandra Roberts, said more than 30,000 people attended the gig, which was pretty good for a Tuesday night close to Christmas.
About 50 per cent of ticket-holders were on the field, the rest on the terraces and embankment.
"Real fans always want to get as close as possible to the stage and action, which was reflected in strong sales for the field area."
The Herald's head of entertainment Joanna Hunkin said concert-goers' age-range easily spanned six decades. "There were families, including one father-daughter pair in matching school uniforms. And, of course, a sea of black T-shirts and glowing, red devil horns."
