A list of passengers travelling on the 3rd May, 1884 voyage of the Tongariro has just been added here, thanks to a listing on eBay. The Tongariro was launched on 23rd August, 1883. In the book Crossed Flags (ISBN 0 905617 87 8), it states that she could carry 64 first class passengers, 36 second class, and 250 in steerage. All 64 first class tickets were sold out for this voyage. She also had refrigerated space for no less than 27,000 carcasses!
