At his first news conference since winning by a wide margin, Mr Schwarzenegger said he wanted to have an independent audit of the state's finances to find out where money was possibly being wasted.
He said he was "unwilling" to raise taxes and promised to scrap a controversial new car tax.
But he also warned that Native American casino operators - who reap annual revenues of $5bn - would have to pay their "fair share".

It is the first time in the state's history that Californians have voted to sack their governor mid-term.
