Light-fingered thieves are putting the safety of the public at risk.
New Plymouth District Council staff noticed that 12 heavy-duty stainless steel bolts had been stolen from a set of stairs near the Coastal Walkway recently.
District council manager parks and open spaces Stuart Robertson says the missing bolts were quickly replaced, but their theft is concerning.
"It's pretty obvious that the bolts are needed to keep the stairs safe to use. We're fortunate that the stairs did not fail and that no one was hurt. We've also had bolts taken from a fence recently."
Stuart says people should ring the council immediately if they notice anyone messing with public structure who isn't wearing branded council clothing or is not a recognised contractor.
