On Friday, a Department of Conservation (DoC) worker found a message in a bottle after it washed ashore on Rangitoto Island in the Hauraki Gulf.
That message was sent by a young girl from Auckland named Olivia.
DoC posted photos of the recovered in a blue bottle and message on Twitter, hoping to find Olivia.
Olivia's mum, Sarah Brown, saw that the bottle had been found and told Newshub her daughter is a keen environmentalist.
"She put the bottle with the message in the ocean at Kohi Beach to see if it would reach another person.
"Despite putting a plastic bottle in the ocean she is a passionate conservationist and wants to be a marine biologist when she's older."
Olivia has been in touch with DoC and they've invited her over to Rangitoto Island to meet the ranger who found her message.
She threw the bottle into the sea on February 26, 2017.
