Historic walkway in New Zealand to be chemically preserved

The wooden remains – described as a find of national significance when unearthed – will be displayed inside the George St shopping complex once they have been treated. They have been soaking in a bath of polyethylene glycol, to strengthen the wood, following the causeway’s discovery during the mall’s construction in June last year.
About 60% of the causeway, made from manuka and kanuka, was previously found too rotten to save.
However, Southern Archaeology Ltd director Peter Petchey, whose firm was contracted by the council to treat the wood, said in a letter the process was expected to take “at least another 12 months”.
