Broom is one of seven changes from the last contracting period.
Reece Young, Rob Nicol, Trent Boult and Luke Woodcock have all been offered contracts for the first time.
Daniel Flynn and Broom return after missing out in 2010-11, while Hamish Bennett has remained as a contracted player after receiving an elevated contract earlier this year.
Brent Arnel, Grant Elliott, Gareth Hopkins, Tim McIntosh, Jeetan Patel and Daryl Tuffey make way, with James Franklin, who received an elevated contract in February, also missing out. Scott Styris retired from all international cricket last month and was not considered.
While Broom told the Otago Daily Times he was delighted to be offered a contract, his goal is to force his way back into the one-day playing XI and make his test debut.
"I'm not getting too excited about the contract," Broom said.
"The main focus is to do well on the New Zealand A tour and push for a place in that test side."
New Zealand A will play a series of three-day games against an Australian side later this month and it is the last opportunity to press for spots on the Black Caps' tour of Zimbabwe in October.
"It is a pretty big tour for me because there is not a lot of cricket after that, so I think a few spots will be selected from that tour."
Broom said he was surprised to get the call from acting national selection manager Mark Greatbatch with the good news. He was expecting to miss the cut.
"It was a bloody good feeling, really," Broom said.
It has been a good couple of months for Broom. His wife, Melissa, gave birth to their first child - son Connor - in April.
Greatbatch told Broom his return was down to some very solid domestic form. Broom had a good first-class season, scoring 645 runs at 49.61 including his maiden double century. He also scored two centuries in the one-day competition.
Greatbatch said the number of new players forcing their way into the top 20 was a good sign.
"Seven changes to the contracted list highlights the fact that there are a number of quality cricketers contesting for the top 20 contracts," he said in a statement.
"That kind of competitiveness is good for our cricket.
"As always, there were some tough decisions and some players with decent international records have missed out. Those players can play their way back into the reckoning by performing at domestic level."
Canterbury all-rounder Nicol had a superb summer and topped the domestic MVP table. Northern Districts left-armer Boult's selection is more of an eye to the future and Young, Bennett and Woodcock made their international debuts last season and will be looking to press for more opportunities this summer.
Players are ranked across all three forms of the game, with test cricket receiving twice the weighting of one-day internationals and twenty/20 internationals. The players with the highest aggregate score are then offered contracts.
