You remember asking if the moa could still be living in the South Island hidden? Well, according to reports, an overstayer German has been hiding in the Franz Josef area for 20 years, and only got caught within the last few days. Impressive.
I believe that's exactly what the authorities have in mind, deporting him back to Germany. But yes, how he managed to evade the police was probably fairly easy, and once he threw them off the scent, he could have lived a semi-normal life.
