Hey Trudi,
you have a great attitude in making sure the solution you arrive at adds value to both the organisation and the team themselves. From your comments above it sounds like you'll have a mix of regulatory requirements to meet in terms of guarding and machinery for which WorkSafe have a number of guidance documents to get you started (https://worksafe.govt.nz/topic-and-industry/machinery/), there are also a number of professionals that work in this space which you can find on the HASANZ register (https://register.hasanz.org.nz/).
With regards hand tools, my advice would be to first have a discussion with all of your staff about what they feel is required, the frustrations they may have around the equipment they're provided with, etc. The purpose being to ensure that they are supported with what they feel is the right equipment, training and resources for the tasks they're already engaged with. From there you will be able to determine what the purpose of any training/sign off is, and include them within the design of your scheme; without this you run the risk of non-engagement and the tick box action you alluded to, regardless of how well intentioned it might be.
Best regards

Andy
