Defence Force lends hand to protect one of NZ's rarest birds

The Department of Conservation and the Defence Force have teamed up to build a nest site for New Zealand's critically endangered fairy tern ahead of the breeding season. This week the Defence Force drove tonnes of oyster shells out to Papakanui Spit, off Kaipara South Head, to build an elevated site for the threatened species. Our reporter Anneke Smith went along for the ride.
