New Zealand police and Wikis

Has anybody heard (read) about the attempt by the New Zealand police to revise their laws and regulations through a Wiki?
I just read a piece in a Spanish newspaper and I was wondering if there is an English version to share with this group. If you are interested I can give you the Spanish-language reference.
What would happen if the faculty were to propose a revision to the administrative structure of the school using a Wiki? How about designing a protocol for the curriculum review through a Wiki?
Precisely.

first experience with wiki not so great

Curious to know how others have done with wikis (wikies?). I created one for my introductory American government class and asked the students to use it to write mock court rulings. The students had a little over a week to do the assignment. They formed 4 groups, each responsible for the equivalent of 2 pages of text.

Two significant problems:

1) About 6 of the 27 students in the class didn't participate.

2) The hoped-for collaborative strength didn't materialize. The writings were choppy, and in a couple of the cases no one took the time to stitch together the various pieces that group members created. Punch-line: the entries read like a bunch of disjointed notes, not like a final document.

You can see the results for yourself (as if you have nothing else to do w/ your time) at iwu-americangovernment.wikispaces.com
