Brockton-based HarborOne Credit Union wants consumers to ditch the big national banks and start banking locally. Preferably with HarborOne.

The credit union has launched a new advertising campaign focused on the benefits of working with a locally-based financial institution, one which touts HarborOne’s roots and commitment to the local community. The ads focus on HarborOne’s local commitment and emphasize that all of HarborOne’s lending and charitable giving occurs here in Massachusetts. The ads note that depositors’ money is invested in the local community, helping people buy homes, build businesses and help support non-profit organizations.

The print ads highlight the fact that nearly 28 percent of all Massachusetts deposits are with foreign-owned banks, as opposed to the national average of 6 percent.

"With all of the turmoil in the financial markets, both here and around the world, it is an ideal time to inform people of the benefits of banking locally," said HarborOne president & CEO James Blake. "Unlike multi-national institutions, our concerns are focused on the people, cities and towns we serve right here."

The $100,000 campaign launched in mid-January. It included print ads in the Brockton Enterprise, the Boston Globe and the Plymouth Old Colony Memorial; radio spots on WBZ-AM and WBMX-FM; broadcast spots on WBZ-TV and Brockton and Plymouth cable networks; and online at boston.com.

HarborOne has extended the media schedule an additional two weeks due to the "overwhelming" response, the credit union said.
