The Super City is downsizing, but the number of job losses and savings is not yet known.
The 6700 Auckland Council staff learned yesterday they face three to five years of "transformation" to deliver the full benefits of merging the former eight councils into a single council.
Council chief executiveDoug McKay said that after 18 months of transition to the Super City, it was time to "change gear as individuals and as an organisation".
Mr McKay, who with senior executives announced the shake-up plan to staff, said there would be effects on jobs but it would be unfair to speculate on job losses.
The council's wages bill is $424 million this year.
The proposed changes will not affect the seven council-controlled organisations.
Asked whether the council would look at outsourcing its call centre overseas, as many private companies have done, Mr McKay said he doubted that would happen, but the council could consolidate the 220 call-centre staff in four main centres into one location.
One change likely to occur is consolidating many of the 3500 council staff housed in seven central city locations to a single location.
