The 55-year-old has multiple sclerosis and is wheelchair-bound, but that failed to stop her attending the New Zealand singer-songwriter's concert at the Glenroy Auditorium last Friday.
She was excited to be watching Dobbyn live on stage.
But little did the Waikouaiti resident know, the best was yet to come. Her husband, Brian, had organised for her to meet Dobbyn after the concert.
''I was so surprised,'' she said.
''He came down and sat next to me after everyone had left, and we talked for about 15 minutes.
''I get quite emotional listening to some of his songs - like all Kiwis do. They're like anthems that only Kiwis get.''
Mrs Fields said Dobbyn held her hand, gave her a kiss and a cuddle, asked her about her illness and gave her some comforting words.
''That made my day - it made my year. It's not every day you get to sit down with a superstar.
''It's hard to keep smiling every day, but having Dave Dobbyn sit next to me and tell me he's thinking of me, makes all the difference.''
Mr Fields said Dobbyn was humble and genuinely interested in his wife's condition.
''He was thinking about her and her situation, and trying to give her some hope.
''It's these things that make him a hero to us.''
Mrs Fields said it had given her the inspiration to continue ''the fight''.
While she got a kiss and a cuddle from Dobbyn, Mrs Fields giggled when asked if she also managed to get his personal mobile number.
''No, we didn't get that far.''
