The data and one of the sub headings indicate a seven year historical data base, but further on in the article it is stated to be a ten year study already that throws doubt on much of what has been reported.
However assuming that the information is generally correct the findings are not exactly unexpected. Walking the back country is completely different to walking the street as you constantly need to watch where you place your feet in the wild. Just look at the percentages of slips falls etc. We all know it, we have probably all had it happen at sometime, momentary lapse foot in the wrong place whoops!
The worrying part is that Health and Safety is looking at tramping. I am just picturing some idealistic public servant proclaiming more signs need to be erected to warm people out and about of the dangers that they face. signs with large arrows pointing to exposed tree roots, warning of mud ahead, slippery surfaces, inclines, beware of wind and that just to avid the tramper in front of you. Do not linger you ma be attacked by an aggressive weta, do not eat the possums from traps, beware of falling trees.
But wait, think of the benefits and the number of jobs that would be created. They would need at least 2000 people a year erecting signs and replacing damaged ones. A whole new economy would be created within the country. People growing trees specially designed to make signs, mills to mill the timber, designers, artists, painters. Oh! What a wonderful environment we will create.
There are some instances where I think some people should stick to their knitting.
