The Lexis Nexis NZ Knowledge Network is the go-to place for all their training and support. Look under the "legal tab".
You can sign up for webinars, read their handouts, or watch videos.
There's a LOT of stuff here.... .
If you need a refresher lesson on specific processes, eg, how to find a statute, you may find the suite of little short videos very useful indeed.
Still stuck? JUST ASK!!!
