Has anyone I know tried this non-Google ReCAPTCHA alternative, ReMAPCHA? https://wiki.hsr.ch/StefanKeller/wiki.cgi?ReMAPTCHA - it appears to ask people to do things that will improve the quality of OpenStreetMaps data... I like the sound of that! Perhaps NZ Gov't could use this instead of Google's service (which is used to train Google's AI, but is quite US-centric).
