So how many of these enforcement officers has the Commission appointed to ensure safe access across its walkways? Someone used FYI, the public OIA request site, to ask them, and the answer may surprise you: zero. They have never appointed any enforcement officers, and have never prosecuted or fined anybody. While police and DoC rangers can also enforce the law, if they had a policy of outsourcing enforcement to those agencies, you think they'd say so. So the natural conclusion is that this agency is simply uninterested in enforcing the law.
Is this a problem? Parliament certainly thought it was a big enough deal to grant these powers in the Act, and refusing to enforce them (even by outsourcing to another agency) seems like a frustration of Parliamentary intent. And if they're not going to bother, then maybe those powers need to be removed, and the job explicitly given to a competent agency which can do it: DoC.
