Extra buses will be put on to help reduce long queues of University of NSW students and staff caused by construction of the $2.1 billion light rail project but erecting extra stops as a temporary solution remains off the table.

The Easter holidays have temporarily alleviated the pressure on bus services to and from the university's campus in Sydney's east.

Students and staff faced waiting up to an hour for buses after changes were made to stops and routes late last month to allow for the light rail line to be built along High Street in Randwick near the university.

About 26,000 people catch public transport to the university on weekdays, and four of the six busiest bus stops in Sydney are between Central and UNSW.
