The cult of "Visina" corresponded with that of Baal and "Rukuruku" with Ashtoreth, the ancient deities signifying the creative and the productive powers of nature – e.g. ruku (the feminine) and sina (native spear grass) the masculine symbol. Thus the name "Nairukuruku" has a relationship and significance to the clans creative totemic symbols towards the feminine fertility. The chiefly clan's totemic plant and animal, the "Vico" – native spear grass and the "Vo loa" – black mud fish is the living heathen symbols to the tribes masculinity and warrior class. Traditionally the Yavusa Siko is "bati" and protectors of the feminine totemic tribes representing fertility such as the Waimaro clan of the eastern highlands. The Siko Natabutale clan's treasured feminine "Radiniwaimaro" statuette in Taulevu village attests to this. Deed of Cession Commissioner Commodore G. J. Goodenough and Reverend Frederick Langham also visited Nairukuruku on 21–22 January 1874 which was then the foremost Christianized village in the upper Wainimala river of Colo East. At Nairukuruku Goodenough makes a proclamation prohibiting white settlers the use of native Fijians especially the belligerent 'Kai Colos' as plantation slave labour. According to Siko Natabutale clan history Ratu Viliame Batiratu representing his elder brother the Taukei ni Waluvu, Ratu Meli Davetanivalu who was frail, was part of the Vunivalu of Bau, Ratu Seru Cakobau's entourage to Levuka Ovalau for cession on 10 October 1874. As a village loyal to the new religion of Christianity and later central government, Nairukuruku was a potential target for attack by non-Christian neighbours resisting Cakobau's interference in their affairs. Nairukuruku became known as "na Bau ni Colo" or "the Bau (island) of the highlands" due to its rise as the seat of political power. It became the call centre for all colonial visitors into the eastern highlands of Viti Levu. The first European females to visit Nairukuruku and indeed the highlands were writer Constance Gordon-Cumming and Reverend Fredrick Langham's wife Ann Elizabeth, who had accompanied the minister to the Christian enclave village where they spent Christmas in 1875.
