Nice set of images! Makes me regret not getting over to Tongariro. I made it cross-country to the top of Mt Ngauruhoe and spent my time between there and Mount Ruapehu. I had a bum knee from bike-riding and did not want to tramp a great distance with a lot of weight, so just took day hikes. Over the New Year, 1987...Tongariro was a little quieter then.
What sort of focal length(s) were you using -- trying to get an idea of scale.
