One of the goals of COMPASS experiment is the determination of the gluonpolarisation, \Delta G/G, for a deep understanding of the spin structure of thenucleon. The gluon polarisation can be measured via the Photon-Gluon-Fusion(PGF) process. One of the methods to identify this process is selecting highp_T hadron pairs in the final state. The data used for this analysis werecollected by the COMPASS experiment during the years 2002 to 2006, using a 160GeV naturally polarised positive muon beam impinging on a polarised nucleontarget. A new result of \Delta G/G from high p_T hadron pairs in events withQ^2>1 GeV^2 is presented. This result has a better precision due to theaddition of 2006 data and an improved analysis based on a neural networkapproach. The gluon polarisation is also presented in three bins of x_G.
