"We've moved over 10,000 trucks in the two weeks since the ceasefire, a massive surge," Tom Fletcher said on X.
The UN Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator added that he himself was "about to cross into northern Gaza with a convoy of aid".
"Thank you to the many people making it possible to get these trucks of vital, lifesaving food, medicine and tents through," he said.
His comments come as Israel and Hamas prepare to negotiate the second phase of the ceasefire agreement, which has paused 15 months of Israeli war and siege on the Palestinian territory.
Israel's war on Gaza has so far killed at least 47,518 people and injured more than 111,000 others, mostly women and children, according to the territory's health ministry, figures the UN considers reliable.
With just a trickle of aid coming into the Israeli-besieged territory before the ceasefire deal, international aid organisations repeatedly reported crisis levels of hunger in the Gaza Strip and warned of looming famine.
The truce has led to a surge of food, fuel, medical and other aid being allowed into Gaza, and enabled people displaced by the war to return to the north of the Palestinian territory.
Under the Gaza truce's ongoing 42-day first phase, 18 captives have meanwhile been freed so far in exchange for some 600 mostly Palestinian prisoners from Israeli jails.
