The 12 youngsters, from all corners of the country, have been tasked with inspiring and mobilising other New Zealanders to know and care about what is happening to the marine environment.
Katrina Jensen, who finished at Palmerston North Girls' High School last year, said she was honoured to be carrying on Sir Peter's legacy.
"As we've been becoming more involved with the Sir Peter Blake trust we've been finding out more and more about him and all the things that he did, which are just so amazing.
"He had a lot of passion for the environment and New Zealand and he actually acted on what his passions were, which is pretty inspiring."
Ms Jensen, 18, will be studying Engineering at the University of Canterbury this year and hoped to merge this with her passion for the environment.
Sir Peter Blake Trust chief executive Shelley Campbell said the Young Blake Expedition aimed to tool them with the knowledge and skills to become the future leaders of New Zealand, as well as to continue the great work of Sir Peter.
The New Zealand yachtsman dedicated much of his life to drawing attention to the critical changes affecting the world's oceans, marine life and sea birds.
The expedition departs Auckland on Monday.
