LAHAINA — Effective Oct. 5, retail hours of operation were reduced at dozens of Post Offices on Oahu, Maui and Kauai.

The adjustment in retail hours is a continuation of the Postal Service’s ongoing efforts to restructure operations and reduce costs, given an unprecedented decline in mail volume and revenue during the past year.

“We regularly evaluate retail traffic patterns to determine the most efficient hours of operations for individual offices,” said District Manager Daryl Ishizaki. “Retail hours can and do regularly change based on customer needs and customer traffic. The goal is to get our products to our customers as efficiently as possible.”

The Lahaina Downtown Post Office is now open from 9 a.m. to 4 p.m. Mondays through Fridays; the branch is closed Saturdays.

Effective Oct. 26, the Lahaina Main Post Office near Lahaina Civic Center will be open 9 a.m. to 4 p.m. on weekdays, and 9 a.m. to 1 p.m. on Saturdays.
