Two people have died and more than a dozen injured during another grisly weekend on New Zealand's roads.

Just after 4am on Sunday morning one person died in a two-car crash on State Highway 12 near Paparoa, Northland.

About seven hours later one man died and a second person was seriously injured in a crash in Whanganui after a car hit a power pole.

The deaths add to what is shaping up to be New Zealand's worst year on the roads in over a decade.
