The remaining area of the Brisbane Water Police District outside of Gosford continued to be administered by the police magistrates until 1906. From 7 March 1906, this area became the Erina Shire, when it was proclaimed by the NSW Government Gazette along with 132 other new Shires as a result of the passing of the "Local Government (Shires) Act 1905". On 16 May 1906, the Shire was divided in to three Ridings (A, B, C) and five temporary Councillors were appointed (John Bourke of Kincumber, John Martin Moroney of Woy Woy, Harold Stanley Robinson of Penang, Manasseh Ward of Gosford, and Alexander Wilkinson of Wyong). The Temporary Council first met at Gosford Courthouse on 13 June 1906 and Manasseh Ward was elected as the Chairman. The first election was held on 24 November 1906 and the first meeting of the elected nine-member Council was held at the Gosford Courthouse on 5 December 1906, with Councillor Ward elected to continue serving as the first Shire President.
