Tuvalu language and culture is expanding following a concerted effort by its community. Members of the Auckland Tuvalu Community Trust, such as Sagaa Malua, attest to the expansion of the ethnic group.

In 2013, a New Zealand census indicated that the Tuvalu population has grown to close to 4000 people throughout New Zealand, where close to 70 percent of this population resides in the city of Auckland.

The island people of Tuvalu opt for upward socioeconomic mobility, and migrate from the Tuvalu islands to New Zealand, where they integrate into the existing community. Yet, once stabilizing themselves in New Zealand, the Auckland Tuvalu Society Trust works with the new immigrants to assist them to integrate and to join both local and larger communities.

Yet the health of the community and its language is still inadequate for sustaining heritage fully, as younger generations are continuously tempted to renounce heritage and to adopt more mainstream practices and languages.

As such, those of the Tuvalu community born in New Zealand are at risk of losing heritage and not becoming socialized into the heritage language. This number amounts to approximately half of the younger generation, a ratio across which speaking Tuvalu in domestic settings and speaking English in domestic settings is divided.

Many members of the older generation direct significant effort toward educating their children in Tuvalu.
