Their message is fun but meaningful, and acting marketing director Tasha Picking says they are role models dedicated to caring for the environment who also understand the tamariki of today.
"As a group we decided that the primary focus of our business project will be educating children about the environment and we settled with the idea of writing a book."
They were also aware that there were few bilingual storybooks on the market for tamariki.
Initially Thirteen7 wrote an English-only version with thoughts to write a bilingual copy down the track.
"We wanted our story to reach Māori kids and so this second version came quickly."
The students said they're proud of their book and they think they have a good chance because their business model ticks the YES range of awards.
Minnika's grandmother Minnie O'Carroll, who lives in Waitara, translated the book, and Madelein Van Rensburg and Rafael Quinones who work for Weta illustrated the book.
