This paper uses data from multiple surveillance systems to describe the experience in New Zealand with the second complete wave of pandemic influenza A(H1N1)2009 in 2010. Measures such as hospitalisation rates suggest the overall impact of influenza A(H1N1)2009 in 2010 was between half and two thirds that of the first wave in 2009. There was considerable regional and sub-regional variation with a tendency for higher activity in areas that experienced low rates in 2009. Demographic characteristics of the second wave were similar to those in 2009 with highest rates seen in children under the age of five years, and in indigenous Māori and Pacific peoples. Hospital services including intensive care units were not under as much pressure as in 2009. Immunisation appears to have contributed to the reduced impact of the pandemic in 2010, particularly for those aged 60 years and older.
本文使用多个监测系统的数据，描述了新西兰在 2010 年经历的第二次大流行流感 A(H1N1)2009 完整波次的情况。住院率等指标表明，2010 年流感 A(H1N1)2009 的总体影响介于 2009 年第一波的一半到三分之二之间。地区和亚地区之间存在很大差异，在 2009 年发病率较低的地区，活动水平往往较高。第二波的人口统计学特征与 2009 年相似，五岁以下儿童发病率最高，毛利人和太平洋岛民发病率也较高。与 2009 年相比，包括重症监护病房在内的医院服务所面临的压力较小。免疫接种似乎对 2010 年大流行的影响起到了降低作用，尤其是对 60 岁及以上人群。
