Countdown's general manager corporate affairs, safety and sustainability Kiri Hannifin says the biscuits were their fastest-selling.
"This year we've nearly tripled how many we have available as they are so popular with our customers," she says.
"It's an easy way to help the important work of GirlGuiding NZ, but a delicious treat as well."
Money raised last year went towards opening new Guiding units, Coleman says, and selling the biscuits in supermarkets meant they could redirect their focus to enabling Kiwi girls to access life-changing opportunities and experiences.
Griffin's is also supporting the cause for the second year in a row and managing director Dan Gilbert says they are proud to lend a hand.
