Privatization is the problem not any kind of solution. It's enriching the wealthy at the expense of everyone else
		
		
	 
Where privatization worked really well was when we had private Building Consultants who were able to process building consents, undertake inspections and instruct Council's to issue CCC's.  As someone who deals regularly with Council's obtaining building consents for over thirty years, when firms like PBC and Compass Building Certifiers were about, council's no longer had a "captive" audience and not only improved their customer service but also kept their fees down.
If there was an issue with some consent documents (say I'd noted a bracing element wrong), a Council officer would identify it, give instructions for a clerk to write a letter, sign it, give it to a supervisor to read, write on it required changes for the clerk to do and then finally post or email it out.... which could be days after the mistake or wrong information was discovered.  The application was then put on the bottom of the pile and the 28 days for processing a consent start again when the information was received back at Council.
If the same consent was going through Compass or PBC and I'd written the wrong brace on a plan, I'd get an email directly from the inspector, change the plan or calcs, email them back the revisions (including an amended Memorandum Cert.) and they'd keep processing it without dropping it down the queue.
Even the way they handled inspections was different.  Say an inspector from Compass came onsite and the builder hadn't finished all the nailing for bracing elements.  The inspector would go to the next site and come back later in the day to finish the inspection and sign it off.... no need to rebook an inspection or pay the extra cost for the inspection.  Council, on the other hand, would fail the inspection, require a new inspection to be booked (which usually takes 48 hours notice) and add the costs for the new inspection on to their CCC bill.  If the inspection was for something time critical, the delays so added up to far more cost when the project couldn't proceed any further until the reinspection was carried out.
Once the last of the private ones went out of business, Council's started to markedly increase their fees and their CS has become crap again.  Auckland Council used to have eight customer service centres... now there are none.
