Abstract: Mangrove cover is increasing in estuaries and harbours in many areas on North Island, New Zealand. The expansion of mangroves has been attributed to anthropogenic land-use change, including urbanisation and conversion of land to agriculture. Rapid expansion of mangroves in the coastal landscape has created discord in local communities over their importance in terms of the services they deliver to both wildlife and people. Some community groups have been advocates for the large-scale removal of mangrove habitat, whilst other local residents oppose this removal. This review paper investigated and discussed pertinent biodiversity and ecosystem services studies based in New Zealand mangroves from 1950 to 2017. Results showed that the majority of biodiversity studies have targeted particular species or groups of organisms, with a focus on benthic invertebrate communities. Deficits remain in our knowledge of this expanding forest and shrub ecosystem, notably the terrestrial component of biodiversity, species community-shifts with landscape fragmentation, and associated cultural values. It is recommended that broader species assessments and a longer-term approach be applied to biodiversity monitoring in mangroves, coupled with Mātauranga Māori (Māori knowledge) and western science for holistic management of this coastal ecosystem.
