Harwoods Hole is a cave system located in the northwest of the South Island of New Zealand, in the Abel Tasman National Park.

Evidence suggests that run-off from an area of approximately 20 square km converged into a stream that then flowed down a dry valley to create what is now Harwoods Hole.

They suspected that The Gorge Creek at East Tākaka was the outlet as the flow rate matched, and green dye released inside Harwoods Hole was soon visible when it emerged at Starlight Cave, so named by the cavers where The Gorge Creek emerged.

[3] On 4 January 1960, Harwoods Hole was the site of the first fatality by a member of the New Zealand Speleological Society when the leader of the caving expedition, Peter Lambert, was killed by rock fall.
