Tuhia he toenga mō tēnei wāhanga - Ko Parkes te tumuaki o mua, ā, ko ia ināianei te tumuaki mō te oranga o te whakahaere aroha Cruse Bereavement Care. I mahi ia hei kaitohutohu me te kaitohutohu i muri i te aitua o Aberfan (21 Oketopa 1966), te hinganga rererangi o Invicta International Airlines Flight 435 i Switzerland (10 Paenga-whāwhā 1973), te ahi o Bradford Football Club
(Mei 11, 1985), te tukinga o te MS "Herald of Free Enterprise" i Belgium (Mati 6, 1987), me te pahūtanga o te Pan American Flight 103 i runga i Lockerbie (Hānuere 21, 1988). I runga i te tono a UNICEF, i mahi ia hei kaitohutohu i te whakaturanga o te Kaupapa Whakaora Whakaora i Rwanda i te Paenga-whāwhā 1995. I runga i te tono a te kawanatanga o Ingarangi, i awhina ia ki te whakarite i tetahi kaupapa tautoko hei awhina i nga whanau mai i te United Kingdom i rere atu i muri i nga whakaeke kaiwhakatuma o te Mahuru 11, 2001, i New York City. I te Paenga-whawha 2005, i tukuna a Parkes e te Awhina i nga Whare Hauora me Ann Dent ki Inia ki te aromatawai i nga hiahia hinengaro o nga tangata i mate i te ruu o te Moana Inia 2004 me te tsunami.
