I recommend using a wooden mallet for carving Oamaru stone.
Woodworking chisels are perfectly fine for carving with Oamaru stone.
This is the best sealer that I could find on Amazon that I would consider to be suitible for Oamaru Stone

You can purchase some small blocks directly from here by filling out the form below. The average sizes are (130mm x 280mm x 90mm for the small block $15.00 per block) and (220mm x 280mm x 90mm, $25.00 for the large block), sizes can vary from block to block. They are a great size if you are new to carving and as you can see in the photo below, you can create a pretty good sculpture within that size.
This is because the stone weighs around 10kg per block and costs approximately $62.00 for freight for one block to be delivered from Christchurch to Auckland. Unfortunately, I do not know of anyone who stocks and sells Oamaru stone within the North Island.

Although the tools below are sold through Amazon. They are the same as the stone carving tools that I personally recommend to my students for carving with Oamaru stone.
These benches are height adjustable which makes them perfect for stone carving. I own the Ryobi workbench and love it, but unfortunatlly it is only sold through Amazon's UK store for people that are wanting to buy it online.
Stanley: Surform Shaver
This is a must-have tool for shaping large areas of Oamaru stone
These are smaller files that are designed for the parts of your sculpture that are difficult to get at. They are also an essential set of tools
Crosscut Hand Saw
This type of crosscut hand saw is my recommendation for cutting Oamaru stone
A very handy saw. Mosty used for sawing after a hole after it has been drilled into the stone.
