For Auckland.... (https://www.aucklandcouncil.govt.nz/building-and-consents/building-renovation-projects/heat-your-home/Pages/install-wall-insulation.aspx)

You will need to apply for a building consent if you're installing insulation in:

an external wall
an internal wall that is a fire separation wall.

You don't need a building consent or a resource consent for any other insulation projects.

Dosent mention replacing existing, so if replacing, Id say no paperwork required.

Here in Dunedin the council have removed at least one barrier for insulating which is the cost - the consent process and inspection/s are free.

The required consent form (note - opens pdf) is also not that arduous, most of it is N/A for just insulation.

My original question around the vapour barrier was raised by this consent form, but have since heard from a friend of the family building inspector that this is not required.

Back to your job - notes:

- you can't just slap GIB up - consult the gib installation document which shows how to install gib in a way to avoid cracking.

- you can't just slap GIB up -there are ways to install it to meet bracing specification(s). This will be more relevant if you go the pucker way and get a design from a LBP.

- while the linings are off , seal gaps around doors and floors with foam sausage and/or expanding foam. The requirement here is to only seal the inner part of any horizontal gap in case water sit on the material.

- get the biggliest rated insulation you can. I wish my house had 6 inch studs.

- plastering is actually not that hard (you don't need a degree to be a plasterer). Have a go at a wardrobe or something and you might be surprised.

Enjoy the benefits of your labours - insulating the walls of our house has made a world of difference to the comfort and that's without changing the glazing.

Thanks for the in depth reply.

I was aware of the gib install requirements and docs and am planning on following them. Lots of good info and videos out there that make it easy to understand.
Had also increased the R value from the minimum specified.

The original intention was to plaster myself but after chatting to some friends, family and colleagues who have done it themselves recently, they all said the same thing - "no problem, it can be done but it'll take longer than you think if you want to get it perfect". One of them was a carpenter who's had previous experience plastering and started doing his own house only to get the pros in.
As I'm working to a deadline (impending new baby) I've been told by the wife not to risk it :)

The nesting instinct is strong so I understand the deadline.

As I mentioned, if you dont want to do the whole room have a go at a wardrobe or something small. The reason it's slow is that people don't practice enough to get fast(er).

I just bashed out a kids bedroom in 2 weeks calendar time which was about 3 days of work time.

FWIW since I usually plaster myself I take care to apply the gib in an easy-to-plaster manner e.g. where possible I use longer sheets to eliminate butt joints. Side/bevel joints are much easier for a learner to do competently.

Otherwise, sounds like you could be all set to go. Got a good place to put your network cabinet?
