Mr McKechnie thought he'd "buggered up" loading the photograph on to Tasti's Facebook page and was surprised when his wife, Teana, asked him about his entry once she had spotted it online a week or so later.
Together with a friend, the contest's winner will travel by helicopter to the Forest Lifeforce Restoration Trust's base in the Maungataniwha Forest, Hawke's Bay, where they will encounter the kiwi in its natural habitat.
Mr McKechnie said it was a priceless prize, so he was relieved his picture actually made it on to the website.
He'll take his wife if he wins.
She gave him the voucher he used to get the tattoo as a Christmas present last year.
Mr McKechnie said he knew tattoos were a thing people regretted if they didn't get right, so he and tattoo artist Eva Harkness (aka Eva Marie) thoroughly developed the concept. Eva, formerly of Wanganui, now lives in Wellington.
"I love New Zealand," he said. "There's just so much to do. Everything you could ever need or want is on your back doorstep. I'm very proud of who we are and I wouldn't change being a Kiwi for the world."
