Thursday last week was the 200th birthday of Captain William Butler, the man who built the home on what is now Butler Point, across the harbour from Mangonui. And more than 50 people, from around New Zealand and Australia, many of them descendants of William and Eliza Butler, William's sister

Twenty-six years after he left England William arranged to have an advertisement placed in a London newspaper, hoping to make contact with his only sister.
"By good fortune, Mary Eleanor Beale was able to communicate with her brother, and emigrated to New Zealand with her family," Ms Ferguson said.
Meanwhile it was with great regret that her parents Lindo and Laetitia were unable to be there.
"Without their foresight 43 years ago none of us would be here now to enjoy this historic house, gardens and a whaling museum," she said.
"Forty-three years ago the homestead was on the brink. It took professional advice from John Stackpoole, architect and historian, and a considerable financial investment by my father to restore this valuable piece of New Zealand heritage.
"In 1970 the property looked totally different than it does today. It was barren. The native bush was unable to regenerate due to the sheep farmed on the property. The pohutukawa standing today are hundreds of years old. Two notable trees planted by William Butler are this magnificent magnolia grandiflora and an olive tree.
"My parents felt a deep responsibility to preserve the history of the property," she added.
"They restored Butler's homestead, created a seaside garden [which is now noted as a Garden of Significance by the New Zealand Gardens Trust], and they sought out a whale boat and collected whaling artefacts to illustrate our history of whaling.
"A significant contribution was made by Janice Mogford's research for the private publication by my father of the book The Butler House.
"There was no furniture left in the house from the Butler family. Some furniture of Hubert Dacre's (who bought the house in 1921) remains, but the rest was sourced from Ferguson and Bell family Victorian memorabilia, here and overseas, to lend credence to our interpretation of how William Butler might have lived - and where he would have celebrated a number of birthdays, I am sure."
Ms Ferguson acknowledged Jan Carr, who had tirelessly searched for those who had received invitations. The celebration included opportunities to look over the museum, house and garden, followed by afternoon tea in the orchard.
