Lost cat needs new home

After two weeks this guy has loved settling into a home. Comfortable staying outside as long as he's being fed, but he also really takes to his minder and shows affection and playfulness. Likes to nuzzle and flop on his back and playfights without claws. He's friendly to other cats if given a chance.
No registered owner but has worn a collar and is already house-trained.
I tried posters, FB posts and lostpet.co.nz but no owner has come forward.
