The Moroccan Association of Human Rights (AMDH) and Algeria's League for the Defence of Human Rights (LADDH) called on the two governments to help the refugees.
The plight of those trapped "is serious enough for the authorities of the two countries to speak at a table to find a solution," they said in the statement.
Women and children are among those who have been stranded in the no man's land since the end of April.
At the time, Morocco accused its neighbour of expelling the refugees to "sow trouble" and "generate an uncontrollable flow of migrants".
Algeria "categorically" rejected the accusations as false.
It sparked a diplomatic spat, with each country summoning the other's ambassador.
The land zone between the two countries has been closed since 1994. The North African rivals have very difficult relations, especially over the question of Western Sahara.
