Wow, that's strong. Luckily it was deep at 44km and no tsunami warnings, right?

Geonet.nz is putting depth at 33 km (± 0 km), and USGS has it at 10 km depth.
The US Tsunami Warning System puts the depth at 21 miles (~33 km)
https://www.tsunami.gov/?p=PHEB/2020/06/18/20170001/1/WEPA40
They did not issue a tsunami warning.

From the USGS summary, it states "The June 18, 2020, M 7.4 Kermadec Islands region earthquake occurred as the result of shallow strike slip faulting near the Kermadec Trench where the Pacific plate begins its descent into the mantle beneath the eastern edge of the Australia plate." I presume there was no heaving or subduction (large displacement) that would induce a tsunami, therefore there was no tsunami warning.
