Bolkow 105 ZK-HAK was mentioned a couple of times in blog posts almost 12 months ago when it showed up at Ardmore, see http://nzcivair.blogspot.co.nz/2012/09/tba-no-more.html
It was back at Ardmore 20 August with the ZK-HAK marks more permanently applied to the tail boom that when first noted in 2012.
Looking like it maybe headed for overseas fish spotting duties was Robinson R44 ZK-HCR. It changed ownership to Western Pacific Helicopters of Wanaka in July this year and wears their name as small titles on the fuselage. Western Pacific have deployed a number of helicopters to Guam over the years in support of tuna fishing.
And last, but certainly not least, was Vans RV-12 ZK-JRV. This aircraft is based at Ardmore and featured on the blog in April this year thanks to Sir Minty : http://nzcivair.blogspot.co.nz/2013/04/vans-rv-12-zk-jrv-at-ardmore-today.html
