The four "value for money" reviews into water, waste, communications and international relations will be discussed at next week's finance and performance committee.
If councillors adopt the recommendations, Goff said immediate savings could be made in communications, plus $13m of savings by combining operations and maintenance of water and stormwater services.
Goff, who promised to find 3 per cent to 6 per cent ($40m-$80m) of spending cuts over and above budgeted savings in his first three years, has struggled with the target in his first year.
While campaigning, he criticised the number of council communications staff and today said he supported a cut of at least 15 per cent over the next three years. This works out at $7m.
"Will it result in fewer staff? The answer is yes," Goff said.
The review found potential savings in communications of $54.5m over 10 years.
The communications and engagement department employs 234 staff at council and across five organisations. It includes media and communications, marketing, research and consultation staff.
Goff said the review found communications was not returning good value for money on marketing and was slow to take advantage of the move to digital communications.
He said savings from the reviews would be reinvested in vital services and infrastructure for Auckland.
Finance committee deputy chair Desley Simpson, who is working closely on a rolling series of "value for money" reviews, said the reviews were "baby steps".
"After the full term we will get significantly more savings," she said.
The water review noted that through amalgamation, the city's water services had saved Aucklanders hundreds of millions of dollars, but more can be done.
About $6 billion to $7b of capital water works are planned over the next decade, and joint procurement and other savings could add up to $300m, Goff said.
The waste review found $165m of savings since amalgamation and a clear plan to reduce household trash, but said there was a need to shift attention to commercial and industrial waste, which account for 86 per cent of the city's rubbished.
The international investment attraction and global partnerships review found the functions are well organised and aligned.
It recommended exploring fees for investment attraction services that benefit the private sector.
The "value for money" reviews are a requirement under the Local Government Act for councils. Goff said group procurement and parks and open spaces will be the next to be reviewed.
Council chief executive Stephen Town said the reviews identify clear opportunities to deliver better value for money for Aucklanders, including working more closely with CCOs on shared objectives, and using group procurement to cut costs.
"They also highlight where we've made significant progress, including by bringing some functions in-house at lower cost, or streamlining services to save ratepayers money.
"Once the Finance and Performance Committee has had the opportunity to consider the reviews and make recommendations to me, we will work to implement the recommendations."
