Mrs Mahoney, whose husband Phillip is deputy principal at Kamo High School, said there were at least seven families with Brazilian connections living around Whangarei.
Her friend Donna Rodrigues, a New Zealander whose Brazilian ex-husband Jorge is a professional footballer in Hong Kong, said that Mrs Mahoney was a key person in the Whangarei's Kiwi-Brazilian community, inviting them all to dinner at her Kamo home and encouraging them to socialise together.
Mrs Mahoney said that after the victory expected this morning some of the group could turn up at her place this evening for a tot of caipirinha, Brazil's national cocktail, made with cachaca (sugar cane hard liquor), sugar and lime.
It didn't taste strong, but if you downed it all at once you needed to find a place to sit, she warned.
With Croatia defeated, the Whangarei Brazilians will begin biting their nails over their team's next game, against Mexico in Fortaleza on Wednesday, kickoff at 7am.
