I te tau 1956 i whakaaetia te whakataunga i te Hui Tuarua o te Huihuinga Nui o UNESCO i New Delhi a i te tau 1957, i hainatia he kirimana i waenga i te Kawanatanga o te Republic Italian me UNESCO ki te whakatu i tenei Whare i Roma.Ko te uru o nga mema o te rima o nga mema o te 1958 i whakaaetia ai nga Ture kia whai mana, ka waiho te Whare hei tangata ture. I whakapumautia te mahi tahi me etahi atu umanga tiaki Pakeha, ara te Central Institute of Restoration of Italy (ICR, inaianei ISCR) me te Royal Institute for Restoration of Works of Art (IRPA) i Belgium. I hangaia he kaunihera mo te wa poto i tohua e UNESCO ki te whakahaere i te Whare, a i te tau 1959, i whakatuwherahia i Roma me Harold J. Plenderleith, Kaiwhakahaere rongonui i te Whare Taonga o Ingarangi, hei Kaiwhakahaere. Ko te kaituhi toi o Belgian, ko Paul Philippot te Kaiwhakahaere Tuarua me te Kaiwhakahaere Matua tuatahi i te tau 1960 i wa i pootihia ai nga mema o te Kaunihera o te Kaunihera o Europi.
