Empowering Students Through Engineering: The EPro8 Challenge

The EPro8 Challenge is an annual, STEM focused, inter-school competition for primary, intermediate, and secondary students. It provides a platform for young people to develop problem-solving skills and explore their interest in science and technology.

Congratulations to Waihī Beach School's junior team, “Beach Mako”, who took first place at the Year 5–6 semi-final, securing a spot in the grand final.

Jessica, ICT Facilitator at Ōtūmoetai Primary and parent of one of the competitors, said “Every kid is so excited when they see STEM on the board. It really is incredible, especially at their age, to be able to do something like this. It's an opportunity they wouldn't have without EPro8.”

Andrew of EPro8 said “Across the country there’s over 30,000 students involved in the program in some shape or form. We've had students who have finished year 13 and competed the entire way through now studying engineering at university, which is to me, that's the really rewarding part, the long-term narrative with these guys.”

This year OceanaGold proudly sponsored 12 events across the Waikato, Bay of Plenty, and Otago regions. Through our support of the EPro8 Challenge, we aim to inspire the next generation of problem solvers and engineers, nurturing innovation and interest in STEM from an early age.

We’re seeking Expressions of Interest (EOI) from suitably experienced local contractors to deliver a package of private residential works and services as part of our proposed new subdivision on our Knowles Crescent/Barry Road property.

The project is still in the planning and approvals phase, so any contract award will depend on approvals being granted and final tender details being confirmed.

We welcome interest from local contractors who can manage and deliver a mix of different types of work, coordinating subcontractors or trades to complete all of the works.

For each residential section, the appointed contractor will be responsible for delivering:
▪ Power and water supply connections from boundary to house
▪ Stormwater detention/soakage pit installations and connection to house
▪ Wastewater connections from boundaries to houses and subfloor drainage
▪ Construction of decking, stairs, balustrades, and baseboards
▪ Construction of residential concrete driveways and parking
▪ Internal fencing and landscaping works.

Replacement Bench Seat on Pit Rim Walkway Installed

Thanks so much to Glenn Rangiuia for rebuilding the recently vandalised bench seat on the Pit Rim Walkway, and to Lloyd McGechie Construction for supplying the timber for the rebuild.

The seat has now been reinstated and is looking great! If you're quick you might even pick up a hint of Linseed oil still.

This bench was one of several installed around the Pit Rim as part of a joint project between the Waihī Community Forum and OceanaGold Waihi, following requests from members of the public for more seating in the area.

A huge congratulations to everyone in the OceanaGold Waihi Mines Rescue and OceanaGold Macraes Operation Emergency Response Teams for their efforts at the Sky Tower Challenge on Saturday.

More than 1,100 firefighters and emergency responders from across New Zealand took on the Firefighter Sky Tower Challenge in Auckland; climbing 1,103 steps while wearing 25kg of gear to raise vital funds for Blood Cancer NZ.

🏃‍♂️ Waihi Mines Rescue Team – 3rd fastest team in the country
🥈 Waihi team – 2nd overall for team fundraising
🥉 Macraes team – 3rd overall for team fundraising
👏 Shay Perkinson (Waihi) – 3rd highest individual fundraiser

With 1,150 participants climbing for a cause, the 2026 challenge raised an incredible $2.5 million for Blood Cancer NZ; supporting Kiwis and whānau impacted by blood cancer.

Also a big shout out to staff who competed for or assisted the local Waihi Volunteer Fire Brigade and Mayor View Volunteer Fire Brigade teams.

This result reflects the dedication of our teams on the tower and the incredible support from our communities, families, and colleagues who got behind the fundraising efforts. We’re incredibly proud of you all! Your commitment to community, teamwork and care continues to make a real difference.❤️

A reminder that the upgrade works near the Gladstone Hill tracks are continuing, with trench works and pipe installations beginning shortly.

Due to the proximity of these activities to public tracks across OceanaGold land, we may need to temporarily manage access to the area to ensure public safety. Signs will advise of any diversions or short-term closures.

All tracks affected by the works will be reinstated once construction is complete, and there will be no ongoing access restrictions.

We encourage you to pay attention to the signage at track entrances and follow any posted diversions. We understand this is a popular recreation area and we will make every effort to complete the works as quickly as possible.

Works to begin near Gladstone Hill tracks

From early March, work will begin adjacent to Gladstone Hill to install an additional water diffuser in the Ohinemuri River, alongside our existing treated water discharge system.

Once the diffuser is in place, crews will excavate a trench and lay a new pipe connecting to our Water Treatment Plant. The work will take place in stages over several weeks, depending on weather conditions.

Due to the proximity of these activities to public tracks across OceanaGold land, we may need to temporarily manage access to the area to ensure public safety. Signs will advise of any diversions or short-term closures.

What is a diffuser, and why do we use them?
A diffuser is essentially a pipe installed in a river, with smaller openings along it that release treated water. The openings point upwards and away from riverbanks, and the pipe does not cross the full width of the river as a precaution against impacting fish migration.

Diffusers are used because they spread out treated water as it enters the river, allowing the water to mix quickly and safely with the river flow.

We have monitored water quality and aquatic life in the Ohinemuri River and its tributaries since 1981, several years before modern mining began.

Monitoring continues today at nine sites around Waihi, both upstream and downstream of our operations, including the Ratarua, Mataura, and Waitete streams and the Ohinemuri River.

More than 30 years of monitoring shows that water released from the WTP has not harmed the river’s ecological health.

OceanaGold staff, contractors, and invited guests joined Company President and CEO Gerard Bond on Wednesday 13 May at a pre-dawn blessing and dedication of the Wharekirauponga underground mine, part of the Waihi North Project.

Once producing, the Wharekirauponga Underground mine will generate over NZ$8 billion of export revenue for New Zealand (estimated at current gold prices). The Company plans to invest approximately NZ$1 billion in the project with about 80% of this expenditure expected to be spent in New Zealand, including over 30% of that within the Hauraki District.
