And yes, I have relatively (to the previous government) high conservation hopes for the new government. Fingers crossed. (I should give some credit for the Kermadec Islands marine reserve here!)
Just to clarify though, my comment was about public sentiment. My anecdotal experience is that Brits are more concerned about conservation than New Zealanders. Which I was quite surprised to discover. And largely I wanted to commiserate with the parent of my comment.
Everyone I know recycles, uses eco and environmentally friendly products where they can, etc. People who I know who fish always fish within the allowed limits and quotas. My grandmother told me over Christmas that she was never going to use another plastic bag.
So, in my opinion, the country is very eco minded, but that sample is skewed because it's only my friends and family. I did meet someone at a party a few years ago who said she just threw her rubbish over the fence onto a council reserve because she was too busy and lived a too important life to bother with dealing with it. There are also people who regularly get caught taking too much paua, or catching underage fish, etc. So obviously they're out there, how prevalent people with disregard to the environment are I don't know, as I said I live in my own bubble.
It could be that people in the UK are more environmentally minded than here, but that wasn't my experience when living there. It could be that they're not but the people that you've met in both countries have simply given that impression.
Someone has probably done a study somewhere.
(First was Yellowstone and second was Royal National Park in Sydney, don't know about the third).
I think you probably meant concerted effort. e.g. That there has been a combined community effort where everyone works together.
Conceited effort means an extremely self-interested effort, which is a plausible meaning, but I suspect it is not what you meant.
NZ is not perfect, and the relatively good state of the environment is definitely helped by the fact that population density is low, espeacialy in the bottom 2/3rds of the country, but there is a strong desire to improve the situation by most, even most farmers are committed to improving the waterways and providing more green area.
