I've certainly continued picking up bits and pieces of the language since then, even if not in dedicated study. maoridictionary.co.nz seems to get visited on a semi-regular basis :-)

I'm glad that I come from a place where resources like that exist and get adequate support and availability. For some of my game-related work, I was looking into some Native American languages and culture recently - it seems a whole lot more difficult to find good online resources available for many of those.
