Abstract: The purpose of the study is to determine the trends of linguistic development in the territory of the New Zealand region within the framework of the redistribution of ethnosociogroups, as well as to assess the linguistic prospects of the southern and northern island parts in a comparative analysis. The article reveals the main extralinguistic factors influencing the linguistic space of the south and north of New Zealand, which provoke evolutionary linguistic shifts with the formation of new variations of the language. The most important comparative characteristics of ethnolinguistic groups are identified and described on the basis of a statistical assessment of their redistribution over the past few years, taking into account covid realities. The subject of the study is the New Zealand language space at the present stage of development. The scientific novelty of the study is to present the current language situation in New Zealand based on a comparison of the changing ethnic and sociolinguistic conjuncture of the southern and northern islands. Official statistical data on the New Zealand region, as well as a socio-ethnic atlas with forecasting up to and including 2038, were used as materials. The study provides a justification for the linguistic shift in the territory of New Zealand, and also presents a summary table of comparative data on the ethnic composition and linguistic groups of the southern and northern regions with an assessment of possible scenarios for future language development in the context of ethnosociolinguistics.
