The Tongan skipper of the sunken vessel MV Princess Ashika said authorities knew the ship had problems but he was pressured into sailing her anyway.

In an interview with 3 News, Captain Maka Tuputupu explained how he has spent the days since the sinking, grieving.

About 95 lives were lost in the worst ferry disaster in the Pacific region.

Captain Tuputupu was trapped on board as the ship went under.
