 On the arrival of Christian missionaries William Cross and David Cargill on Lakeba in 1835, an announcement of their mission to Taliai Tupou was made and accordingly they were conducted to Matailakeba, his heirs' house, while the purpose of their coming was once again explained.Vuetasau approved and Taliai Tupou in turn followed suit and the missionaries were allowed to stay and establish a church.Vuetasau never succeeded to his uncles title as he drowned in 1857 whilst in an expedition with Tongan Chief Enele Ma'afu.
