Hello Chris, sorry about that! I'd not checked to see that the information was up there. We are currently rebuilding an easier format to navigate, as finding stuff has been an issue.
I've now pushed it up the pile and the link can be found on the home page "what's hot" www.nzfwda.org.nz
I suspect that Virginia has vegetation growth problems too that close over trails. We have to constantly cut the sides of many of our trails otherwise they can virtually disappear. It's also a concern when an agency closes an area for review or even if there's been land movement limiting access.... the growth in some areas can almost obliterate a trail within a couple of years.
