This paper reports cross-section measurements of 𝑍𝑍 production in 𝑝𝑝 collisions at *%𝑠 = 13.6 TeV at the Large Hadron Collider. The data were collected by the ATLAS detector in 2022, and correspond to an integrated luminosity of 29 fb*−*1. Events in the 𝑍𝑍 *> 4l (l = e, *m) final states are selected and used to measure the inclusive and differential cross-sections in a fiducial region defined close to the analysis selections. The inclusive cross-section is further extrapolated to the total phase space with a requirement of 66 < 𝑚𝑍 < 116 GeV for both 𝑍 bosons, yielding 16.8 *{ 1.1 pb. The results are well described by the Standard Model predictions
