Three volcanoes - walks I prepared earlier

Last year I actually managed to walk up three of Auckland's volcanoes, so I can already tick off:

• Mt Roskill (cannot find out the Maori name) - surprisingly steep and you have to walk through the cows (and their pats) which is quite fun
• Mt Albert (aka Owairaka) - a bit dull, but had a nice picnic at the top
• Pigeon Mountain (aka Ohui-a-rangi) - quite small, I've always wanted to climb this one because of an historic association with OAR YMs which is based at the bottom of the hill.

I've also found a handy map of Auckland's volcanoes on the ARC site (and learnt how to spell volcanoes correctly as a result). Some of those listed are of course craters rather than hills, eg Lake Pupuke. I'm not sure how I'll tackle those as I know you can't walk around all of them due to private property on the lake/basin edges.
