"When the wharenui opened, there were three days of celebration," says William. "It had been built to unite the people of the area, and stood 24m long, 12m wide and 7m high."
Filled with beautiful ornate carvings and masterfully crafted, Mataatua was indeed worth celebrating ... but the celebrations weren't to last long.
"The New Zealand Government decided that the wharenui was so beautiful that it should be shown to the rest of the world," says William. "Against the wishes of the people, it was dismantled and taken to the 1879 British Empire Exhibition in Sydney."
"There is was reassembled inside out, so the carvings were on the outside and at the mercy of the weather, which caused much damage. After Sydney it was taken to London and erected in the Kensington Museum in 1881, and was stored in the Victoria and Albert Museum for many years. It returned to Aotearoa in 1925, but not to Whakatane. Instead it became a permanent exhibition at the Dunedin Museum."
It was only in 1996 that a Waitangi Tribunal Special Deed of Settlement saw the wharenui return home, and it was officially reopened last year.
Now fully restored, the Mataatua Wharenui is a fascinating place. Visitors are welcomed by members of the iwi, given a guided tour of the wharenui, and introduced to the ancestral carvings on display.
There is a truly spectacular light show inside the wharenui, and my experience ended with a feast of kawakawa tea, potato bread and manuka honey.
Next day I'm up early for the trip to White Island. I've always wanted to visit this geothermal hotspot, and the cloudless day is ideal for a boat trip. The people at White Island Tours have been taking brave souls to this volcano since the early 90s, and they know how to keep punters happy.
This is whale and dolphin territory, and the captain has an eagle eye out for these delightful mammals. Sure enough he spots a pod of tiny common dolphins, and passengers are soon "ohhing and ahhing" with delight as the creatures frolic in the bow wake.
We eventually anchor near the island and we clamber on the inflatable to go ashore. Kitted with gas mask and hard hat, I'm confronted by a moonscape. Rocks and stones litter black sand; sulphuric residue paints the ground fluorescent yellow; steam rises from sinkholes filled with bubbling water. It's a truly sinister place; you can almost feel the ghosts of the poor miners who were killed when a massive lahar wiped out all their buildings in 1914.
After 90 minutes on the island, I'm glad to get back to the boat and the packed lunch. The trip back is relaxing and fun; the whole day has been truly memorable. I know the big sky and the beautiful landscapes of eastern Bay of Plenty will draw me back; Whakatane has worked its magic.
