Summary text ftciteseerx 2016-01-07T18:18:26Z The number of humpback sightings and the number of whales recorded in this study suggest a slow increase over the last 10 years, particularly in the last 4 years. The results of this study may have been influenced by a variety of factors, the most important of which may be inconsistent effort. The results presented in this report are broadly consistent with that described by Dawbin (1956). As reported by Dawbin (1956), and found in this study, the northern migration occurs between May and August while the southern occurs from September to December. There is little evidence of a change in migration patterns past the New Zealand coast. The inability to quantify effort is a major limitation with the data and does not make it possible to draw clear conclusions on population size or trends in migration. However, the results are useful in determining the locality and seasonality of humpback whales as they migrate along New Zealand coasts. 1.
