He had many clashes with other councillors but also won the support of others and at one time, during the mayoralty of Bob Francis, created a council faction that basically split the council in half.
Mr Goodwin was often a critic of the level of funding council gave to the Aratoi Art and History Museum and regularly questioned the accuracy of museum visitor figures.
He didn't shy away from questioning other council big spends, including building and maintaining the rec centre.
In 2004 he claimed millions of dollars of council reserve funds had been siphoned off to prop up projects like the rec centre and to meet the cost of a cryptosporidium outbreak to disguise what otherwise would have been rate increases.
In 2009 he raised the testy topic of councillors' attendance at meetings, revealing the then top-polling councillor, Edwin Perry, had the worse attendance record.
Ironically Mr Goodwin and Mr Perry were both shock casualties at the elections the following year.
