With the Gorkha outfit slated to hold a meet with the Mamata Banerjee-led government Nov 20, Gurung said the main meet agenda will be ensuring no interference in the working of the GTA.
Gurung has often accused the Banerjee government of interfering in the working of the GTA and even threatened to "repeal it at an appropriate time".
He also said the GTA will soon start recruitment process to fill 4,000 vacancies.
"Our agitation for Gorkhaland will now go to Delhi and we will put pressure on the central government for Gorkhaland," added Gurung.
Armed with more powers than its predecessor - the Darjeeling Gorkha Hill Council formed in the late 1980s - the GTA was created July 18, 2011 via a tripartite agreement between the GJM and the central and state governments.
The GJM swept the GTA's maiden elections in 2012.
