His family said Newton-Jones, a doctoral psychology student, had experienced mental health challenges in the past but recently spoke optimistically about the year ahead.
Newton-Jones, born in Dunedin, trained as an engineer before changing careers in his mid-20s to pursue psychology.
He was in the final stages of completing his PhD and passionate about helping children and young adults overcome adversity.
Police were hoping anyone who spotted Newton-Jones on the Mercer Bay Loop Track or around Piha would come forward.
He also visited the walking track on Monday, and anyone who saw him that day was encouraged to come forward.
Newton-Jones is about 185cm tall, wears glasses, and was last seen in a white shirt, black pants, and black sneakers.
His family has asked Piha residents, in particular,to keep an eye out for him.

The area has been linked to several mysterious disappearances over the years, including two women who vanished after visiting the same walking track.
