Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: I muri i te whakakorenga o Crisp i te 1997, ka neke a Sia ki Ranana, i reira ia i mahi ai hei kaiwaiata papamuri mo te roopu Pakeha a Jamiroquai. I whakaratohia hoki e ia nga kaiwaiata mo te roopu downtempo Ingarihi Zero 7 i runga i a raatau pukaemi studio tuatahi e toru ka haereere me te roopu. I runga i te pukaemi 2001 o te Zero 7 Ko nga Mea Maamaa, i uru a Sia ki nga waiata e rua: "Destiny" me "Distractions". Ko te kotahi "Destiny" i eke ki te Nama 30 i te UK Singles Chart. I te tau 2004, i whakaratohia e ia nga reo mo Zero 7 i runga i te "Somersault" me te "Speed Dial No. 2" (mai i te pukaemi When It Falls). I te tau 2006, i mahi tahi ano a Sia me Zero 7 mo te pukaemi tuatoru o te roopu, The Garden, no reira ka kiia ko ia te kaiwaiata rangatira "kore mana" o Zero 7.I te tau 2000, i hainahia e Sia he kirimana rekoata me te tapanga o te Sony Music Dance Pool ka tukuna tana takitahi tuatahi, "Taken for Granted", i eke ki te Nama 10 i te UK Singles Chart. I te tau 2001, i tukuna e ia tana pukaemi takitahi tuarua, Healing Is Difficult, e whakakotahi ana i te jazz retro me te puoro wairua me te korero i nga korero a Sia mo te matenga o tana aroha tuatahi. Kaore i pai ki te whakatairanga i te pukaemi, ka peia e Sia tana kaiwhakahaere, ka wehe atu i a Sony Music ka haina ki Go! Beat, he kamupene o Universal Music Group (UMG). I nga Tohu APRA o te tau 2002, i wini a Sia i te waahanga Waiata Waiata i te taha o Jennifer Waite me Grant Wallis o Brisbane pop duo Aneiki.I te 2004, i tukuna e Sia tana pukaemi studio tuatoru, Colour the Small One. Ka whakamahia e te pukaemi he ranunga o nga taputapu puoro me te tautoko hiko ki tana taonga. I puta mai i te pukaemi nga waiata e wha: "Kua kore e kawe mai i ahau ki raro", "Hohoro mai", "Kei hea ahau" me "Numb". I eke a "Breathe Me" ki te Nama 71 i te United Kingdom, Nama 19 i Denmark me te Nama 81 i Parani. I whakaritea te "Where I Belong" kia whakauruhia ki te puoro oro mo te kiriata Spider-Man 2; heoi, na te raru o te waitohu rekoata, i tangohia i te meneti whakamutunga. Kaore i makona ki te hokohoko kore o Colour the Small One me te uaua o te pukaemi ki te hono atu ki te hunga whakarongo nui, ka neke a Sia ki New York City i te tau 2005. I taua wā,  Pātai: he aha te mea kei roto i te pukaemi kaimahi?
he whakaranu o ngā pūrere oro me te tautoko hiko ki tōna rauemi
