Jonathan 1?'s posts are concrete.

20 years ago the timber treatment was CCA Tanalising. The problems with copper and zinc interacting still existed but not as bad as the newer treatments that have more copper in them.

Anything on a wharf was probably wrapped in Denso tape or heavily coated in pitch.

Yeah, but his railings and palings aren't.

I was aiming that at nick800 who mentioned 90mm posts.

For the twisting post problem the following yt video demonstrates using a car jack to pull the post out of the ground leaving just the original hole.

Heh. I'll keep that in mind if mine needs looking at again.

CCA is still the standard as far as I am aware, has the treatment changed much?

Galvanized bolts seem to last fairly well as opposed to screws, depth of coating, surface contact likely reasons. Though for a balcony you I can see why stainless might be required.

Our neighbour decided he wanted to paint the newly installed pine fence black. I warned him.... Two years on it's twisting apart and given its 40m long, it is going to cost him an absolute fortune to replace.

Fek - our neighbours want to paint their side of the fence (the one I'm about to build) black, so I'll be damned fixing it in a few years if it's warped because of their colour choice! Will make this clear from the outset, so thanks for the warning!

See this article from BRANZ, the recommendations are probably now part of building code.

Galvanized nails don't work so well in ACQ treated timber (i.e. the stuff that won't poison your garden, pets or children. As much). 

 

In Bunnings (Wellington Bunnings at least), ACQ-resistant screws and nails are now prominently advertised. Of course, there isn't any ACQ timber to buy, but surely that is a mere trifle!

For the black fencers, Resene Cool Colours are an option. Advertised to absorb the visible light spectrum, but reflect the infra red that is responsible for overheating, warping and general degradation.
