The bubbly brunette quit her job in Thames, Coromandel, a month ago and has moved in with Deans in West Auckland, with their new ridgeback staffy dog called Fiddy.
She has started a new job at an Auckland real estate agency.
"We are all shacked up and it feels so right," she said. "Dan is a friend of a mutual friend.
"He is a Westie and and we hit it off straight away. The chemistry between us is amazing."
Tattooed tradie Deans - who Kininmonth says is a keen hunter - proposed to her within a week of their first meeting. He got down on one knee and presented her with an engagement ring after they kayaked to secluded Saddle Island in the Hauraki Gulf last month.
"We went for a walk after a picnic and I noticed he was suddenly very nervous," she explained. "I said 'yes' and we plan to get married in Papua New Guinea next year."
Kininmonth insists her dramatic departure on The Bachelor wasn't staged.
"I went on to the show genuinely looking for true love but Arthur wasn't the man for me," she said. "He is very good-looking and I loved his height because I want to have tall kids.
"He is a nice guy, but when he said he did not want to come to the Middle East with me and be my bodyguard, that was the deal-breaker."
Kininmonth prefers the outdoor types like Deans, whom she described as "a man with a hunting knife between his teeth and who will take me fishing and camping".
"Dan has also promised to take me to all the dangerous places in the world I want to go."
Kininmonth also plans to start a plumbing business with her fiance.
"Life is too short to have any regrets and I hate wasting time," she said. "I want to experience everything I can, while I can. Before I die, I need to become a millionaire but just now, I'm so excited to have found real love."
