"I have such fond memories of eating Choco-ade bikkies with my nana when I went to stay with her as a kid. They were our little treat. Biting into them today brings back all those special memories."
Mrs Johnson has been involved in the production, flying up to Auckland to take part in a taste test at Griffin's Papakura factory.
She was keen to make sure the new biscuit is as close to the original as possible, especially as they are now manufactured by machines, not handmade as they were in the 1980s.
She will also front a TV advertisement.
Griffin's marketing director, Josette Prince, said the company discontinued the biscuits in the early 1990s to pave the way for new products.
"With so much support and passion, we couldn't help but listen and so Choco-ade biscuits are back and New Zealanders have Amber Johnson to thank for this great Kiwi comeback," she said.
The first 50 packets are being auctioned on Trade Me and the proceeds will go to Plunket, Mrs Johnson's chosen charity.
