Mr Berry said he believed Mr Palino's policy positions make his own candidacy unnecessary for this election cycle.
"That's why I am now endorsing John Palino to be the next Mayor of Auckland."
Mr Berry was the Affordable Auckland candidate for Mayor in 2013 where he finished third behind Mr Palino, taking nearly 4 per cent of the vote.
Voters currently have three centre-right candidates to choose from -- Mr Palino, businesswoman Vic Crone and Orakei Local Board member Mark Thomas.
Mr Palino said he had been speaking with Mr Berry and was glad he was throwing his support behind him.
Asked about the centre-right being cluttered, Mr Palino said it made things difficult "but at the end of the day it is a democracy".
Labour MP Phil Goff is the leading candidate on the centre left. Other candidates include former Green Party member David Hay, activist Penny Bright and lawyer Adam Holland.
