    Analysis of seasonal trends in the Drought Code in New Zealand

    H. Grant Pearce and Meredith A. Whitmore
    Trends in DC values for a number of stations from several regions of the country were investigated to determine whether concerns that values of the DC component are increasing over time in New Zealand due to calculation issues, particularly a lack of annual re-setting, or possibly climate change.

    Proposed Revision of Fire Danger Class Criteria for Forest and Rural Areas in New Zealand

    Martin E. Alexander
    An updated edition (with corrections, including an amendment to Table 1a) of Marty Alexander's 1994 report on the criteria used to define the fire danger classes in New Zealand. The report is divided into two separate parts for the convenience of the reader: Field Application, and Research Documentation. The Field Application section is for those interested only in the practical aspects of applying the criteria, whereas the Research Documentation section is for those who are interested in how the criteria were derived, and the procedures involved, mathematical analyses and associated philosophical discussion.
