Pecten novaezelandiae is found on sand, silt, and mud from low tide level to over 90 m. Large populations are found at depths of 10 to 25 m.[1] Pecten novaezelandiae is completely free-living, mobile and somewhat migratory.

However, in Tasman Bay / Te Tai-o-Aorere, the peak time is from November to March.

Metamorphosis occurs and the larvae changes from planktonic to a benthic existence by attaching itself to suitable substrate on the seafloor.

Recreational and commercial fishing of this species is allowed at particular times of the year, the scallop season.

In some areas of suitable habitat, such as Tasman Bay / Te Tai-o-Aorere, scallop spat is seeded in an attempt to achieve a sustainable fishery.
