Buildings still standing on the island have been weakened after Sunday's natural disaster.
"There are still some evacuees that have not yet been touched by aid, especially in North Lombok and West Lombok", Nugroho tweeted Thursday.
A strong quake hit Indonesia's Lombok island on Thursday, causing some buildings to collapse. Panicked residents fled into the streets, witnesses said.
The United States Geological Survey (USGS) recorded the latest quake at 5.9, with a depth of 10 km (6 miles).
Buildings still standing on the island have been weakened after Sunday's 7.0 quake that killed at least 131 people and a 6.4 quake on July 29 that killed 16.
Disaster agency spokesman Sutopo Purwo Nugroho said in a statement that information being provided by different agencies needs to be complete before it can be cross-checked and officially verified.More news: Family from Westchester in Indonesia when massive quake struck
Tens of thousands are now sleeping out in the open or in the ruins of their homes. Water, food and medical supplies were being distributed from trucks.
Rescuers have found three bodies and also managed to pull one man alive from the twisted wreckage of the mosque, reduced to a pile of concrete and metal bars, with its towering green dome folded in on itself.
The quake was the second in a week to hit Lombok.
The military said that five planes carrying food, medicine, blankets, field tents and water tankers left Jakarta for the island early on Wednesday.
Most people live in basic housing in small communities.
With hospitals and clinics also affected, numerous injured have had to be treated in the open air or in makeshift clinics.
Workers with heavy machinery are searching the rubble of homes, schools and mosques, with hope of finding any survivors fading. In December 2004, a massive magnitude 9.1 quake off Sumatra triggered a tsunami that killed 230,000 people in a dozen countries.
