The light station was originally home to three keepers and their families. In the mid-1950s when diesel-generated electricity was introduced to power the light it was dropped back to two keepers. By 1977 only one keeper was stationed at the lighthouse.

Centre Island Lighthouse remained a one keeper station until the light was automated in 1987.

During World War Two, coastwatchers were stationed on Centre Island and equipped with confiscated ham radio equipment:

Consequent on the need for coastwatching communications, was the need to silence and control other non-essential radio traffic. The first emergency regulations, passed in 1939, five months before the war started, prohibited radio receiving station licensees from recording or publishing information gained from the airwaves. With ten days of the state of emergency being declared on 1 Sept, some amateur radio hams were losing their equipment ‘for the duration.’ Messrs Hazlett and Sutton Invercargill both lost their sets because they continued to use emergency corps callsigns ZL4EF and ZL4GX respectively. Their sets went to Army use on Centre Island in Foveaux Strait as callsigns ‘RFP’ and ‘RFM’, codenamed ‘Jako’ and ‘Cato’.
