The second "wildcard" contender for Survivor NZ has been chosen by the public.

Auckland journalist and social media manager Franky March, 24, was voted onto the show by the public after a stint managing radio station ZM's Snapchat account.

March was up against 22-year-old Auckland nanny and office manager Angus Blyth.

Both ran ZM's Snapchat profile for a day – doing whatever came naturally, but ultimately trying to win the hearts of listeners.

Listeners and viewers then voted for which of the two they wanted to see on Survivor.

While it came down to the wire, it was March who secured her place as a season 2 castaway.

She said just running ZM's Snapchat had caused her to face her fears - and she was looking forward to pushing herself further on Survivor.

"If there's any reality TV show I would enter, it would only be something physically and mentally challenging – something that would drive me to my limits and bring out the best in me. Life throws you funny things now and again, this is one of them.

"The Wildcard challenge has already made me face one of my biggest fears - what other people think and say about me. In terms of actually surviving in the wild for 40 days, I can't wait to see what I am really made of."

March joins fellow "wildcard" contestant Kaysha Lahana, who was chosen through a similar competition on ZM's sister station The Hits.

Survivor NZ puts New Zealanders stranded on a remote island against each other and their environment, with the winner taking home $250,000.
