The annual state of the nation speeches are an opportunity to present key messages to voters - and attack the Government on perceived weaknesses and failings.
Labour and the Greens have signed a formal memorandum or understanding to work together until the election.
Little said he would not announce new policy on January 29.
"You can expect to see one or two joint policy announcements in the next few months between Labour and the Greens.
"There are plans to do that in different sort of ways. One of them is to get around the country with a joint policy statement - talk to a collection of audiences right across the country on a policy area that we have common ground on. People will see that as the year wears on."
There are significant differences between Labour and the Greens on policy. In July, Green Party co-leader Metiria Turei was the first party leader to explicitly call for a fall in house prices, saying she wants to see house prices fall by 50 per cent over 10 to 15 years.
Little responded by saying he disagreed with that approach and it wouldn't be happening under a Labour Government.
Today, he denied a joint state of the nation event could result in voters looking at the two parties as one and the same.
"We have differences and we have common ground. But what they will see is, here are two parties presently in opposition who are committed to strong, stable Government as an alternative to the present."
Green Party co-leader James Shaw said the parties felt there was more to be gained than lost from holding a joint event.
There were differences between Labour and the Greens, but Shaw said the two were now in a "pretty close working relationship" and wanted to show the public there was a credible and ready alternative to National.
Shaw said during the election campaign the different policies between the parties would be obvious, and this was about stressing to the electorate that Labour and the Greens were ready to work together.
