Since the 1970s, the New Zealand National Museum Te Papa Tongarewa has been issuing demands for the return of mummified Māori heads (toi moko) despoiled during colonisation. 'Objects' of many statuses and definitions, toi moko generate different representations and symbolise many cultural visions or practices. As a place and actor of restitutions, the museum is the central space of the dispute. As one of the poles of the decolonial process, the Te Papa Tongarewa Museum bears the claims of its population as well as the bicultural policy of the New Zealand state. Similarly, the Quai Branly-Jacques Chirac Museum exemplifies and territorial- ises, through the restitution ceremony of 23 January 2012, these returns that confront different perceptions of heritage. This article examines the ways in which these museum institutions bring together all of these parameters and actors in order to carry out the returns of Māori human remains to Aotearoa, allowing us to question this museum revival in a decolonial context of heritage and culture.

Pulse-wave propagation velocity and resonance frequency measured in civil engineering structures are both related to structural design. Monitoring their variation following seismic strong shaking provides information about the immediate building capacity. Joint-interpretation of frequency and velocity variation requires a better understanding of the processes controlling seismic structural health. In this study, we analysed 8 years of earthquake data recorded by the vertical array installed in the Te Puni building in Wellington, New Zealand, as part of the GeoNet building instrumentation programme. Co-seismic variations of pulse wave velocity and fundamental frequency are analysed and interpreted through a Timoshenko beam-like building model. This study shows that even though no structural damage was visually reported over the considered time of monitoring, co- and post-seismic variation of both parameters' values are observed for almost all earthquakes, including a permanent shift following strong ground shaking. Variations of pulse-wave velocity and resonance frequency are cross-interpreted in terms of the building model. They reflect a time variant building response, correlated with the seismic loading. In addition, time delay of the pulse-wave velocity as a function of the building height provides relevant information on the location of the changes and confirms the efficient cross-interpretation of both methods for seismic Structural Health monitoring.
