Tourism Holdings shares jumped after its Discover Waitomo business was named as one of the first recipients of the government's $400 million tourism support fund.
The Waitomo caves operation will receive up to $4m to keep the business alive as the nation's borders remain closed through the Covid-19 pandemic.
Tourism Holdings shares rose 10.6 per cent to $2.40 in early trading, taking their gain so far this week to 33 per cent.
The government's Tourism Sector Recovery Plan set aside $400m in the Budget for the industry to help cushion the blow from Covid-19 and position the sector for recovery.
Tourism Minister Kelvin Davis said Discover Waitomo's application for funding had been fast tracked as there was an "urgent need" for cash.
