Nope. "Picking up pennies in front of a steamroller." comes to mind.
Don't get me wrong, CSC is a great initiative and sets a solid foundation to build a sustainable freedom camping framework. The changes could be construed as minor tweaks that strengthen an already robust foundation or......
Applying it retrospectively is unwarranted. The only time in NZ that regulation changes are applied retrospectively is significant safety risk, this change is being applied retrospectively, those who built up vehicles to the standard of the time, are being penalized though no fault of the own. I also have a concern it sets a dangerous precedent - they can change the standard anytime they like and your next CSC your vehicle may no longer meet the standard. Once they have go small vans off the road, they might put UK Caravans with portable tanks n the sites, then maybe converted buses. "First they came for the socialists...."
OTT? Time will tell, hopefully they stop at the sliding doors.
However, if we put that concern aside, lets get back to the steam roller
The problem is on top of the foundation (CSC) - it's a house of cards made from toilet paper (pun intended). The issues we read about are not caused non-CSC vehicles. Its caused by freedom campers. Strengthen the CSC standards and increasing the numbers of CSC vehicles won't fix the problem. The CSC standard provides a tool to help fix the problem, but making a better tool when your not even using the one you have to its most effective is pointless. The issues are caused by the number and behavior of freedom campers. Far too many freedom campers think CSC is badge of entitlement and a license to figuratively crap on the rights of others, these tend to be the same people that believe not having a CSC means you literally crap on others.
The focus has to shift to the philosophy of "Leave not trace" (Look up the movement), which focuses on choices and behavior. Concepts such as choosing to avoid locations that are under pressure, confining damaging activity to locations that can sustain it are whats needed. Every freedom camper leaves a trace - your visual foot print might disappear when you leave, but the memory of you visit takes longer to fade. Your tires tracks in soft grass might fade in time - but 100 tires do not. The rut might already be there, but do you need to make it bigger? Things like deciding to stay at an NZMCA park rather than the grassy campsite down the road because its been raining for a week make a small difference. Lots of us making a small difference makes a big change. LNT is not about sticking to the rules and regulations, its about dong more than the minimum - doing the right thing.
The good news is (I believe) the NZMCA recognizes this and is working hard to move on from the 'Badge of Entitlement' mindset some have with the little blue sticker represents. Much more needs to be done, especially among this community, NZMCA cannot carry this alone.
Don't be alarmed when you see me talking to myself, I am getting expert advice.
