Armour rocks are being stacked up in a Morgan St yard, ready for the repair of Whanganui's North Mole.
The repair is Horizons Regional Council's part of the $50 million Te Pūwaha project to revitalise Whanganui's port, and there have been security concerns at the Castlecliff storage site, a spokeswoman said.
The yard's entry gates have been stolen and its fence damaged, and fuel and batteries have been stolen from an excavator at the site. People seeing inappropriate behaviour there are asked to ring the police or contact Horizons on 0508 800 800.
The first rocks brought to the site are the smallest of four sizes that will be used in the mole repair. They are volcanic andesite from a consented quarry inland from Ōpunake.
Later, similar rocks will arrive from a consented quarry north of Raetihi. The contract to supply them went to Mills-Albert Ltd, a Kāpiti forestry and construction business, working with Byfords Construction, Loaders, and River City Tree Services.
