Groundwaters of New Zealand attempts to bring together in one volume a complete reference guide to groundwater research and resources in New Zealand. It was written to provide a state-of-the-art snapshot of groundwater research, ideas and developments, and current and historical references that encompass the entire country. To this end, this well written, illustrated, and documented book is a grand achievement. However, given its size, the book could do a better service by providing a perspective of New Zealand groundwater research and management in relation to practices outside of its borders. With that said, the book is admittedly written with updates in mind, which means that future additions can address areas of advancement and concern as needed.
