Capai vs kapai

Back at my own keyboard for the first time in 3 weeks,(and home 30 minutes after a 40 hour trip) I'm pleased to have an easy one to start with. "Kapai", in Maaori, does indeed mean "AOK", in the sense that "ka" is acting as an intensifier for the root word "pai", which simply means "good". This makes it seem unlikely, at least to me, that the similiarity is anything other than a phoentic coincidence.
