The two adult Sumatran Tigers at Hamilton Zoo seem to be getting on well in their enclosures, following a tiger swap last year.

The swap saw OZ trade places with Jaka, Hamilton Zoo's previous male Sumatran tiger.

Zoo director Stephen Standley says the relationship between OZ, and the female tiger Sali has been developing over recent weeks.

He says the zoo keepers were not sure how they would interact, but says the animals seem to be getting on well together and are developing a good relationship.

Mr Standley says it's too early to tell whether the two tigers will breed successfully.
