In 1858 the General Assembly made some significant changes to electoral boundaries and increased parliamentary representation from 37 members to 41. One of the changes meant the Wairarapa and Hawke's Bay electorate was split into its two separate components (with both Wairarapa and County of Hawke expanding inland into previously unincorporated areas). County of Hawke was represented by two Members of Parliament, James Ferguson, incumbent in the seat as member for the previous Wairarapa and Hawke's Bay electorate and Thomas FitzGerald from 26 April to 5 November in 1860 after winning the 1860 by-election.
The second Parliament was dissolved on 5 November, and FitzGerald did not seek election to the new Parliament. He had been elected Superintendent of the new Hawke's Bay Province in 1859. He moved to Queensland, Australia in 1862.
In 1861, the new Napier seat was formed in Hawke's Bay.
