But she did not feel confident in qualifying for such a role to represent the community.
"She said to this woman - you know the community, you live in the community, you are qualified."
Ms Marsters said she now had the time to "stop thinking about it and doing it".
She visited the Napier City Council website to reacquaint herself with the current councillors, who she said had achieved some good things for the city. But she was left wondering if the council reflected the diverse communities within Napier.
She said she had learned that although her wider family possessed their shared values they often had different perspectives and saw things differently.
"I bring to this election other perspectives," she said.
"I believe the opportunity to consider and appreciate other perspectives, other ways of thinking, seeing and doing needs to be at the decision-making table of our city council."
Ms Marsters stopped short of using the word "challenge" when it came to summing up her approach - preferring to say she "won't step back" when something needed sorting and doing.
"Let diversity be the change."
