The two events are 28 years apart, but walking through abandoned and mould infested parts of Tauranga City Council's headquarters evokes memories of the Chernobyl nuclear disaster, according to one current councillor.

Earlier this week councillors, including Steve Morris, were given a guided tour of council's Willow Street premises to gain an insight into just how bad the outbreak of toxic black mould, or Stachbotrys, really is.

Following the tour, including the administration area and library, Steve took to Twitter, saying: 'A first look inside TCC's leaky staff building. The latest of a few little legacies left to us by previous councils.”

Attached to this post was photos of the inside of the now vacant administration block due to the mould outbreak, some two months on from the December 15 outbreak.

The photos show patches of the black mould along the floor and the skirting boards as well as areas of the ceiling, which is swollen from leaking.

Speaking to SunLive about the tweet and the images, Steve says having finally been allowed to have a look, comments to him regarding the mould outbreak being minimal are well off the mark.

'I have worked in some pretty grotty places as well as some pretty flash places overseas,” says Steve. 'But none of them have water pouring out of the ceiling or walls on a dry day.

'There was thing kind of Chernobyl feel. It sort of felt like we were going on a tour through reactor four.”

Taking aim at previous councils, Steve says the leaky building issue is just one of a number 'skeletons” left by the previous groups.

He says along with the mould issue, the current council are left to deal with replacing an outdated IT system, a number of failing sea walls and the Mount Cosmopolitan Club, left vacant since 2009 when council bought it in an arrangement clearing the way for the nearby Mount Greens project.

Surveyors are part way through surveying the mould infested building to identify where the water was leaking in, and will be finished the process sometime in March.

Steve says there will be a number of options presented to council following this report, but high on his list of priorities would be ensuring the building is well and truly water tight and seismically strengthened.
