Waihi Gold Mine Day Trip from Thames: Martha Pit, Pumphouse and Mine Tours
The Waihi gold mine is about 54 km from Thames, roughly an hour's drive through Paeroa. Its Martha Mine open pit sits right beside the town centre, and you can walk around its rim, see the historic Cornish Pumphouse and, from Thursday to Monday, join a guided mine tour from the Gold Discovery Centre. Gold was first found at Waihi in 1878, and the mine still works today, underground.

How far is Waihi from Thames?
Waihi is about 54 km from Thames, and the drive takes about an hour. The Thames-Coromandel District Council's travel-time table gives Thames to Paeroa as 33 km (35 minutes) and Paeroa to Waihi as 21 km (25 minutes). From Paeroa you follow State Highway 2 east through the Karangahake Gorge, so the two make an easy day out together. For other routes, see getting to Thames.
Can you visit the Waihi gold mine?
Yes, in three ways. The Pit Rim Walkway loops around the edge of the Martha open pit, the Cornish Pumphouse stands on its own reserve on Seddon Street, and the Gold Discovery Centre runs guided tours inside the mine's security fence. The modern mine works underground, and the tours take you inside its security fence.

Martha Mine Pit Rim Walkway
The walkway follows a fenced path around the top of the Martha open pit, with views down the terraced walls. The Free Walks NZ guide puts the loop at 3.9 km and about an hour, starting near the Cornish Pumphouse. OceanaGold's community newsletter said in May 2026 that recent changes on the pit's south wall do not affect the walkway.

Mining in the open pit has stopped. Wikipedia records that it reopened as an open pit in the late 1980s and that landslides in April 2015 and April 2016 stopped mining there. According to OceanaGold, the company now mines the Martha Underground beneath the area and is developing the Waihi North Project, which received its permit in December 2025, with tunnelling expected to start in the first half of 2026.
The Cornish Pumphouse
The concrete shell on Seddon Street is the Cornish Pumphouse. Wikipedia says it was built next to the Martha Mine in 1904 to house a large Cornish steam engine that pumped water out of the mine. As the open pit grew, the building was moved to a safer site 300 m away: work began in 2006, and the 1,840 tonne structure was slid over three months on Teflon-coated concrete beams to where it stands today.

Waihi Gold Discovery Centre and mine tours
The Gold Discovery Centre at 126 Seddon Street, opposite the Pumphouse, is also the Waihi isite. It is open daily from 10am to 4pm (phone 07 863 9015). It sells three experiences:
| Experience | Length | Adult | Child | Family (2+2) |
|---|---|---|---|---|
| Waihi Gold Experience | About 1 hour | $36 (15+) | $18 (5 to 14) | $90 |
| Waihi Gold Mine Tours | About 2 hours | $69 (16+) | $34 (5 to 15) | $172 |
| Gold Story Tour (both) | About 3 hours | $94 (16+) | $47 (5 to 15) | $235 |
The Gold Experience is a hands-on exhibition where you can play a game of Two-Up and feel the weight of a gold bar. The mine tour runs Thursday to Monday at 1pm, takes you inside the mine fence, and needs covered shoes. The centre recommends booking, and children under 5 go free. Prices were checked on the centre's website in November 2026.
Goldfields Railway: Waihi to Waikino
The Goldfields Railway runs heritage trains on six kilometres of the old line between Waihi and Waikino. Its booking page lists return fares of $25 for adults and $15 for children aged 5 to 16, with under 5s free. Trains do not run every day: the November 2026 timetable has none on Mondays or Tuesdays, and times change month by month, so check before you plan around it. At Waikino you can join the Karangahake Gorge Historic Walkway.
