Fonterra is gradually getting tankers to isolated dairy farms after Cyclone Gabrielle.

An update from Fonterra confirms that tankers are getting to Northland and the Cormandel, but getting to Hawke's Bay is still challenging.

Severe damage to the roading networks between Hastings and Wairoa has made it difficult for vehicles to move through the region. 

The Country's Jamie Mackay says that the economic costs and damage from Cyclone Gabrielle are likely to rank up with the Christchurch earthquakes.
