Allister Jenks has seen this Eurocopter EC 130 B4 ZK-IWS multiple times over several weeks on the Wellington Waterfront. 

It seems to have taken over duties from the aptly-lettered ZK-IWN that has been plying trade there for a long time. So either IWN is out for maintenance, or this machine is now assigned to Wellington ?

 ZK-IWS is  c/n 4041 and was test flown in France as F-WWXI prior to going to Canada to become  C-GSDA with Eurocopter Canada Ltd at Fort Erie, Quebec.

It went on to serve with Great Slave Helicopters Ltd and its subsidiaries until cancelled on 19-02-2016 for export to NZ.

It became ZK-IWS on 22-02-2016 briefly listed with City Link PT Chopper Operations Ltd of Cambridge and going on line with Helitranz Ltd from 10-05-2016. It was returned to City Link from 16-06-2017 then on to Independent Helicopters Ltd of Christchurch from 17-08-2017.

Current operator GCH Aviation listed it from 20-05-2020.
