The current government doesn't believe in regulation. Red tape is believe they call it.
In the real world it's called safety, planning, protection, guardrails, common sense for the good of everyone and the environment.
Definitely some that should be looked at.
When you're installing a roof, you're required to have a safety net to (i) prevent the installers falling when there's a danger they might fall more than 3m and (ii) stop roofing material from landing on someone. But, the regulations don't take into account what type of roof is being installed.
Also, the netting isn't required when the trusses, rafters or bracing is being installed but when purlins/battens, roof underlay and roofing materials are being installed.
The problem is that plywood substrates for the likes of torched on materials (i.e. Butynol and other membranes) and under asphalt shingles as its installed as its a form of bracing as will as supporting the cladding so the netting isn't required until the roof finish is applied to the plywood. But why? Installers can't fall through the plywood and nor can the roofing material fall through it. Yet, the builder/developer/owner has to go to the expense of putting in safety netting which serves absolutely no purpose.
And the council building officers know this but it still doesn't stop them issuing fines (up to $4,000... nice additional revenue source for council) and/or shutting projects down until the unnecessary netting is in place and has been inspected/approved by a council official.
Oh, and it's not the government but MBIE through the Acceptable Standards of the Building Code who determine "safety, protection (on building sites) and guardrails"... so those are safe from Seyless's Minister of Cuts.
