Three quad-bike deaths in Northland in eight weeks will be investigated by a coroner to check for common links that could help prevent similar future fatalities.
Northland Coroner Brandt Shortland will hold inquests into the 2010 deaths of Arapohue farmer and builder Carlos Mendoza, 52; Marua farmer Jack McInnes, 64; and Suzanne Claudia Ferguson, 62, who all died after quad-bike accidents on farms within eight weeks of one another.
Mrs Ferguson was towing a trailer of haylage when her quad bike is thought to have rolled on steep terrain, pinning her underneath on August 9, 2010, at a Gammon Rd farm near Awarua, about 20km south of Kaikohe.
Mr Mendoza died on September 16 near Dargaville.
Mr McInnes died on September 25 when the quad bike he was using to spray weeds rolled on him at Marua.
