One car escaped, but the other was bashed about.
The elderly driver of the damaged car was in quite a state after what could have been a far more serious smash.
Construction management Professor John Tookey said after viewing the video, there were issues with the way the scaffolding was constructed.
“Part of the run which had been put in place was unsupported and unbraced which led to oscillation in the wind, and ultimately collapse,” he told Newshub.
Scaffolding qualifications are a must-have for some jobs, but not all. And the devil’s in the detail, according to Prof Tookey.
“Whenever you use the phrase ‘as far as is reasonably practical’, then you create an opportunity for the less scrupulous to potentially cause significant problems,” he said.
And the scaffolding industry body SARNZ (Scaffolding, Access and Rigging New Zealand) wants to see everyone accredited.
“The barrier to entry – and this is the wider construction industry as a whole – is just non-existent,” said Tina Wieczorek, general manager at SARNZ.
“And this is something we’ve been in active dialogue with not only the previous Government, but with this Government also, and unfortunately what we saw yesterday is a by-effect of that.”
