When asked to face photographers in the traditional fists-up fighter's pose, Elder-Holmes said: "Oh, I hate this."
Elder-Holmes has said she wants to honour her late boyfriend Connor Morris on Saturday. Today she wore the official event T-shirt with the message "Connor Morris 2/11/87-3/8/14" on the back.
Morris, a patched member of the Headhunters gang, died following a head injury suffered during a confrontation outside a party in the West Auckland suburb of Massey.
Adams, Elder-Holmes' opponent, was not present at the press conference as she is filming. She won't be at the official weigh-in on Friday either, but a Duco Events spokesman said her weight would be recorded on Saturday morning.
Elder-Holmes, 26, is a slight favourite at the TAB over 20-year-old Adams at $1.80 versus $1.95.
The pair will fight in the first bout of the night about 8pm, with the main event of Joseph Parker versus Brazilian Irineu Beato Costa Junior expected to start about 11pm.
Also on the undercard are Monty Betham v Carlos Spencer, Jeff Horn v Robson Assis, Willie Mason v Ben Tameifuna and Dave "Brown Butterbean" Letele v Loni "Tongan Bear" Uhila.
