One Sun in the Sky is a hugely important contribution to our understanding of New Zealand history. It is rational, reasoned and evidence based. The case it presents on the issue of sovereignty is particularly pertinent in light of the way the Treaty of Waitangi is being interpreted and enacted into legislation today. This book deserves a widespread readership.

- Peter Williams, media commentator, former TVNZ broadcaster

One Sun in the Sky is magnificent – scholarly, logically-argued, and extremely informative. Based on solid research, its qualities are enhanced by the clarity of its prose. The first chapters are extremely valuable because they show how the Treaty’s language conforms to the way in which words such as ‘sovereignty’ and ‘governance’ were used and understood in 1840.

One Sun in the Sky is a valuable contribution to the debate around how we should interpret the Treaty of Waitangi. In particular it offers useful insights on how the key texts about sovereignty and chieftainship were likely to have been understood by the original signatories and in the years which followed. A nuanced and interesting read.

One Sun in the Sky is well researched and beautifully written. At a time when major constitutional changes are being advocated based on the Treaty, this book offers analysis and commentary critical to charting our way ahead as a nation.

- Warren Snow, businessman & former CEO of the Tindall Foundation

One Sun in the Sky is an excellent work of scholarship, very well researched and convincing in its argument. The Treaty settlements process has been welcome and necessary. However, there is a now a critical need for clear thinking on the issue of sovereignty. This book provides just that. It is a timely contribution.
