The Central Otago District Council announced earlier this week it would move the library from where it shares facilities with the Maniototo Area School library, on school grounds, to the council services building in Ranfurly by mid-July.
The rally, between 3pm and 3.30pm on Monday, is to show support for the school's board of trustees' call for a review of the decision.
A petition for the library to remain in its present location started yesterday and received more than 100 signatures in its first hour, Maniototo businesswoman Amie Pont said.
She said she had been contacted by many people in the community about the issue and the rally was to show concern about a lack of communication over the decision.
It had been ''made behind closed doors and behind the cloaks of confidentiality'', she said.
School principal Patsy Inder and Maniototo Community Board chairman Mark Harris had earlier said that neither group was consulted during the council's decision-making.
The council made the decision at a private meeting on February 25.
Mrs Pont said the Maniototo community would prefer to work with the council, but questioned how they could trust the council when they were not consulted on issues such as the library.
Anyone was invited to the meeting, including representatives from the council, she said.
Under the council plan, the library would be moved to the service centre by mid-July and facilities and services provided by the library would be modernised.
The jointly operated and funded library has operated at the school since 2000.
