When sea-levels rose, the estuarine waters of the Tāmaki River breached the lake, turning it into a tidal estuary.

It features in traditional Tāmaki Māori stories as the eating place of the taniwha Moko-ika-hiku-waru.

[4] The headland between the basin and the Tāmaki River was the location of the Ngāti Pāoa pā Mauināina (also known as Maunga-inaina and Taumata-inaina).

[6] In February 2008, scientists announced that drilling had discovered a scoria cone buried within the mud filling the explosion crater.

[7] Although newspaper journalists inferred that the discovered scoria cone was a much younger and different volcano from Panmure Basin,[8] geologists consider that the scoria cone was produced as the second phase of the eruption of Panmure Basin explosion crater and tuff ring.
