I doubt you could rack up 50,000kms a year crawling in Auckland traffic so chances are it’s been on fairly long hot runs, which would be a plus - keeps the top end cleaner.
If the servicing has been regular, and not scrimped on, should be all good.
Not totally km related but I would check how much life is left in the major wear items like tyres, pads, rotors, etc as they could add a few $$$s soon if they are well down.
