Whakaotihia te rerenga e whai ake nei: I te Paenga-whāwhā 2003, ko te kaiako matua o te kapa motu a Morten Olsen i karanga a Kahlenberg ki te kapa mo te wa tuatahi. I tiimata ia mo te tiima a motu, i uru mai hei whakakapi i te meneti 76, i te wikitoria hoa 1<unk>0 ki a Ukraine i te 30 o Aperira 2003. I te Poutu-te-rangi 2004, i karangahia a Kahlenberg ki te kapa matua kotahi ka puta tana tuarua mo Denmark, ka uru mai hei whakakapi i te meneti 78, i te hinganga 2 <unk> 0 ki a Spain i te 31 o Poutu-te-rangi 2004. I te marama o Mei 2004, i tohua ia hei kaitakaro taitamariki o Denmark mo te
2004 Pākehā Championship. Heoi, kaore a Kahlenberg i purei i tetahi keemu i te whakataetae, i te mea i whakanohoia ia ki runga i te peeke whakakapi.
