He says there are only two others who have done the same as part of Occupy Auckland.
He treats the occupation as a job, getting up at 7am every morning and is at his desk by 8am as a co-ordinator, responsible for the occupation finances, ensuring money donated by the public is put to good use. He says the protest receives about $3000 to $4000 a month in donations.
