New Zealand's largest infrastructure project for many years is on target for completion by the end of the year.
A 186km electricity transmission line will run from Whakamaru in south Waikato to Auckland when the national grid upgrade is finished.
The project was first announced in 2004 and drew opposition from landowners opposed to the new pylons.
Project manager Ian Ditchfield says a huge effort has gone into consulting and compensating landowners.
He says the $824 million project is running to budget so far.
As part of the work, the Arapunui-Pakuranga line, a smaller grid line built in 1940, has been removed.
