In the 1980 I few Air New Zealand quite a bit. First Class on their transpacific routes from Auckland was a great experience. In spite of the slightly
daggy cabin design, the sheep skins of the seats were very comfortable. The food was good, the drinks selection good, and the service always outstanding. Highlights were the spacious
toilets - a size never seen again since then until on Air France's La Premiere more recently - and the arguably best shaving cream I every received as part of any inflight amenities.
P.S. Air New Zealand abolished First Class many years ago and does not offer this top-tier facility any more.
