The Southern Cross cable's 8000km link between New Zealand and Hawaii was completed last week.
The link between Auckland and Spencer Beach was completed on October 17, when the cable ship CS Vercors made the final splice 4600km north east of Auckland.
Southern Cross expects to begin laying the final segment of Phase One — between Hawaii's Big Island and San Luis Obispo, California — on November 27.
The laying of the Auckland-Hawaii link was carried out by three cable laying vessels.
The CS Nexus commenced a 3306km lay from Spencer Beach, Hawaii on September 3 and the CS Innovator began its 1371km lay from Takapuna, Auckland on September 5.
The Vercors then spliced onto the Innovator's cable end on September 27 to commence laying of the remaining 3318km.
Phase one is scheduled to be ready for service in June 2000.
