For governance purposes, the entire parish is within the regional municipality of Tracadie. Before the formation of the regional municipality in 2014, Saumarez Parish included one town and twelve local service districts, with an additional special service area within the parish LSD.

Tracadie is a member of the Acadian Peninsula Regional Service Commission (APRSC).

The parish was named in honour of Sir Thomas Saumarez, acting Governor of New Brunswick when it was erected. Six of the parishes erected simultaneously in Northumberland County in 1814 were named for prominent British military figures.

Saumarez was erected in 1814 as part of Northumberland County from unassigned territory. It included all modern Gloucester County except Beresford Parish.

In 1827, all of the parish west of Teague's Brook was erected as Bathurst Parish.

In 1831, Caraquet and New Bandon were erected as their own parishes.

In 1855, Inkerman was erected from the northern part of Saumarez. The barrier islands east of Tracadie Bay were included in Inkerman.

In 1870 the barrier islands south of the Old Tracadie Gully were returned to Saumarez.

In 1881 a large area along the northwestern boundary was included in the newly erected Saint-Isidore Parish.

In 1947 the western end of Saumarez was included in the newly erected Allardville.
