I think it depends upon where you are actually. I would get a fluro yellow vest or jacket to increase visibility from a distance when touring.
if you come to the Nth Is, we are in Wellington which is where you'd come in on the ferry or by plane. Makara Park is a great place to get off road.

If you want to meet up with other cyclists for a ride or a meal, do PM me & I can show you around.
