I te marama o Hepetema 1942, i tukuna a Catterns, he rangatira, ki New Guinea me te &lt;a href="2/1st%20Battalion%20%28Australia%29"&gt;2/1st Battalion&lt;/a&gt; i reira i kite ai ia i te mahi i te Kokoda Track
I riro i a ia he Karauna hōia, ā, i whakahuatia ia i roto i ngā karere mō ngā mahi toa, nā te rangatira o tōna poari, nā Te Koronela Paul Cullen, i whakatenatena ki te kī "ko te mea maia rawa atu i kite ai ahau i tētahi tangata e mahi". I mahi a Catterns i New Guinea mo te toenga o te pakanga, i te mutunga ka eke ki te taumata o te rangatira.
