This review on the benefits of marine parks is essential reading for anyone engaging in the complex process of establishing a network of marine protected areas.
More than fishy business, published in January 2011 by University of Adelaide, offers a great overview of what's involved behind the scenes: perfect for those who are relatively new to the world of marine conservation who need just that bit more information to help them talk about marine parks with confidence. Bear in mind this is an Australian paper so while principles apply, New Zealand legislation is obviously a little different and there are other variables that may not be covered here.
The second paper here is essentially a catalogue of the successes: Science shows marine parks work. Indisputably. If you need facts at your fingertips, this is the paper for you.
