Since 2011 the wetlands have been managed by Te Nohoaka o Tukiauau/ Sinclair Wetlands Trust. This comprises up to eight volunteer Trustees, including representatives of Te Rūnanga o Ōtākou, and of the Tatawai Whenua Tapu Trust that manages an adjoining portion of the wetland.

As coordinator, Glen Riley lives on site, runs management and education programmes, assists visitors, and supervises the many volunteers who come to help. Revegetation involves the propagating, planting-out, and looking after native trees that are replacing broom and gorse on the islands within the wetland. Pest control targets introduced mammals which prey on native species and plants (e.g. rats, weasels, stoats, ferrets, possums and rabbits). Weed control is targeted at woody scrub weeds, willows that invade the swamp, and reed sweetgrass (Glyceria maxima) that chokes water channels.
