The 4th New Zealand Contingent was one of ten contingents of New Zealand volunteers for service during the Second Boer War. It served from April 1900 through to June 1901. The contingent went from New Zealand to Beira, Portuguese East Africa in the SS Gymeric, though there was a "mutiny" on the Gymeric in Lyttelton Harbour on 27 March 1900 over conditions on board. When they arrived in Beira, part of the contingent was sectioned off to form battery units. The Fourth Contingent left South Africa in the SS Tagus in June 1901.
