Non-avian translocations include 60 tuatara in 2003, Duvaucel's gecko in 2006 and a large insect wetapunga in 2011. Non-native species still present include the Australian brown quail. The success of the conservation project encouraged the creation of a number of similar projects around the Gulf, such as on Motuihe, Motuora and Motutapu. The closest land on the tip of the Whangaparaoa Peninsula, Shakespear Regional Park has recently (2011) also become a mammalian pest-free fenced sanctuary, increasing immigration of the birds on Tiritiri to the nearby mainland.
