DNA polymerase is an enzyme that finctions best when itis placed in the right ionic environment. All buffers and all other constituents required for the PCR reaction are added first. The buffers ensure the maintainace of the correct ionic environment for the polymerase to function optimally. Therefore, the DNA polymerase is added last AFTER addition of template and primer

DNA polymerase is added last in PCR to prevent it from degrading prematurely due to the high temperatures used in the denaturation and annealing steps. This helps ensure that the polymerase remains active and is able to efficiently synthesize the DNA during each cycle of amplification.
