On 29 August 2012 an Agreement between Tuvalu and Kiribati concerning their Maritime Boundary, was signed by their respective leaders that determined the boundary as being seaward of Nanumea and Niutao in Tuvalu on the one hand and Tabiteuea, Tamana and Arorae in Kiribati on the other hand, along the geodesics connecting the points of latitude and longitude set out in the agreement.
These objects, designated Municipal Cultural Properties of Tamana in 2008, are on exhibit at Renge-in Tanjō-ji.
Tamana, in collaboration with Deakin University, Australia, launched TOBY (Therapy Outcomes by You) Playpad Laboratory on the 5th of July 2013 at its Autism Center, School of Hope.
