In an earlier Instagram post about his time in New Zealand, Smith admitted the opportunity to travel was one of the reasons why he wanted to become a musician.
He revealed: "Travelling is to me one of the most important things in life. It's of the main reasons why I chose this career path. What's the point in living on this earth and not seeing it!!!! I am so aware though that many people don't get opportunities to see places like this and would love to!! Deep chats, real chats. (sic)"
