Haymet Rocks
The Haymet Rocks were reported by J.E. Haymet, master and owner of the cutter Will Watch, when on passage between Auckland and Rarotonga; in 1863 the cutter passed between two rocks and struck on the northern of the two, damaging her false keel. The rocks are said to extend over a space of about a quarter of a mile, to have been distinctly seen, and with apparently of water over them. Haymet gave their position as, which would place them about west of the position assigned to Orne Bank.
These rocks were unsuccessfully searched for, in the position given, by HMS Satellite in 1886, and again by the French Government vessel Fabert in 1887; the latter vessel spent three days in the search under favourable circumstances of wind and weather, running over some within a radius of from of the position assigned, and with no result. A depth of to the rocky ocean floor was found by the Fabert at.
In December 1882, however, a Lloyd's agent at Rarotonga reported that the Haymet rocks were supposed to exist about SSW of Rarotonga, and therefore right in the track of vessels bound from Auckland to that island, who always give this supposed position a wide berth. If this information is correct, these rocks are about NNW of the position as given by Haymet and still shown on the charts.
It was suggested that the Haymet Rocks were a remnant of sunken island Tuanaki.
