Police searching for a missing Invercargill boy and his stepfather will meet this morning to decide their next step.

Mike Zhao-Beckenridge and his estranged step-father John Beckenridge have been missing for around two weeks.

They're thought to be in the Catlins.

Car parts connected to the disappearance have been found scattered along Curio Bay.

An in-water search was called off yesterday due to rough weather.

Police are still appealing for sightings of the pair.
