A giant stainless steel milk silo, one of the biggest in the country, has been on the move in Canterbury.
The 28-tonne silo was being transported from Christchurch to Fonterra's newest factory at Darfield between 3am and 7am on Friday.
It's one of 22 being assembled on the site. They'll be used to store the raw milk delivered by tankers, for making milk powder products.
The silo can hold 500,000 litres of milk and joins two others the same size, standing at 22 metres tall and six metres in diameter.
The rest are at least half the size of the big three.
The manufacturer, the Mercer Group, has been building the silos since September, and will finish delivering them by the end of the month.
Christchurch branch manager Ross Coppard says it takes two weeks to plan the 50km trip from its workshop to the Fonterra factory.
He says the silos are moved in the early hours of the morning so it's less disruptive, and a crane will be used to unload the silo.
