For this reason I belive most codes would limit dropping concrete to about 3m, beyond that a tremie should be used. Having said that I expect that the pile was reinforced by a cage on the circumference and that the rebar would not be considered dense, in this case 6m does not seem excessive.
As mentioned in other replies this is only in the case that the pile is "dry". For future castings a tremie is adviseable.
