ARolfe on Family Tree Circles

My great great grandfather was Arthur John Rolfe Born in 1876 here in Tauranga. His father was Charles William Rolfe who came over with the 1st Waikato Militia in 1864 and married Mary Anne Haua (nee Condron, later Linton) in 1875. Mary had Charles, James, Andrew & Pheobe Haua from a previous marrage. Charles fathered Arthur and his sister (also called) Mary Elizabeth with his wife Mary Anne.
Arthur married Mary Anne Harding in 1898. Mary's parents were George and Jane (nee Watson) Harding. George came out under the employ of G.V. Stewart in 1874, Jane and young children came out on the "Dorette" the same year and were quarentined in Auckalnd for Scarlet Fever.
Am trying to find out more about the Harding side and Rolfe (Charles and prior etc). Any help would be greatly appreciated.
