(CNN) -

Chris Christie's headed back to New Hampshire, again.

The New Jersey governor and chairman of the Republican Governors Association will headline a fundraiser for the Granite State's GOP at the end of July. For the possible 2016 Republican presidential contender, it's the second straight month he'll visit New Hampshire, which holds the first primary in the race for the White House.

Christie will be the main attraction on July 31 at a fundraiser for the state Republican Party at the minor league baseball stadium in Manchester, home to the New Hampshire Fisher Cats. Christie will mingle with Republican contributors at a rally style event before the game, followed by top donors (paying $2,500 each) joining the governor to watch the game from a skybox.

Last month Christie briefly visited New Hampshire, and raised money for Walt Havenstein, the leading GOP gubernatorial candidate to take on Democratic Gov. Maggie Hassan in November.

The trip was Christie's first to New Hampshire since the 2012 election. If he does run for the 2016 GOP nomination, winning the Granite State's primary is considered crucial for Christie. Word of the new trip was first reported by WMUR and Politico.

Christie and Sen. Rand Paul of Kentucky were tied at the top of a crowded pack of potential GOP presidential candidates in a Suffolk University/Boston Herald Poll last month of New Hampshire Republicans.
