Nevill was born in Nottingham, England, and educated in Nottingham and at Magdalene College, Cambridge where he graduated B.A. (second class Natural Science Tripos) in 1865, and M.A. in 1868, being created D.D. in 1871. Ordained in 1860, he was Curate of St Mark, Scarisbrick then rector of Shelton, Staffordshire, where he served until his elevation to the Episcopate.
In 1871 Nevill accepted the bishopric of Dunedin. He was consecrated in the pro-cathedral, Dunedin, New Zealand, by the Primate (Harper) of Dunedin and Bishops Suter of Nelson, Hadfteld of Wellington, and Williams of Waiapu. Dr. Nevill twice since revisited England to attend the Lambeth Conferences. Nevill was married at Heavitree, Devon, in 1863, to Miss M. S. C. Penny. When rector of Shelton the Bishop held a certificate of the Science and Art Department of South Kensington qualifying him to instruct candidates for examination under the Department, and was thus instrumental in laying the foundation of the career of some who have attained positions of eminence.
Nevill was Primate of the church in New Zealand from 1904 until 1919 (having been acting Primate since 1902). At his death, Nevill was the senior bishop of the Anglican Communion; he was buried at St Barnabas Church, Warrington.
The Nevill Chapel of St. Paul's Cathedral, Dunedin is named after him. St Paul's has a carving depicting the Bishop holding a model of the Cathedral's proposed design. He died in Bishopsgrove, near Dunedin, New Zealand.
