Club Physical owner Paul Richards alleged Holder had breached franchise agreements that had "years to run on them".
Late last week, Richards entered an application to the High Court seeking an injunction to block Jolt Fitness from trading.
Lawyers for both sides appeared today to discuss the application before Justice Rebecca Ellis, who directed an urgent, half-day fixture be scheduled in next week for the case.
Richard Beddie, head of Fitness NZ, last week issued a general letter stating the importance of gym franchises honouring their contracts.
"We believe allowing franchise operators to break franchise agreements without due regard for contract law would be both without precedent, and more significantly, damaging for our industry."
Beddie said he has not seen the contract between Club Physical and Jolt Fitness, and therefore could not say whether it had been breached, but his main concern was for affected gym members.
