Brooke was a founding player of the Southerners Sports Club, playing in the inaugural side in 1994 against Taradale RFC. In 1995 he published his autobiography Zinny: The Zinzan Brooke story, written with Alex Veysey. Brooke is considered one of the best number eights to have ever played for the All Blacks. He had the running and kicking skills of a backline player which made him extremely mobile and agile as a forward. He once kicked a 48-metre drop goal during a 1995 Rugby World Cup match, one of three he scored in test matches. In the 1997 New Year Honours, Brooke was appointed a Member of the New Zealand Order of Merit, for services to rugby. Brooke scored his third drop goal during the All Blacks' impressive 42–7 win against Wales at Wembley Stadium on 29 November 1997, giving him the rare distinction of being the only rugby player to have "scored a goal at Wembley". He also set up a try for Christian Cullen. In 2007, former England centre and captain Will Carling published his list of the '50 Greatest Rugby players' in The Daily Telegraph, and ranked Brooke the ninth greatest player of all time, stating:
"For a forward his skills were outrageous. As comfortable playing sevens as 15s, he had better kicking and handling skills than some fly-halves playing international rugby. You align that with his strength and ability as a forward to read the game – he was unique".
Retirement
In 1997 he retired from international rugby union and moved to England to play for Harlequins, and later coach it. During the 2002/03 season he played for Coventry in National Division One. He now plays amateur rugby union for WindsorRugby Club in Berkshire, England. In 2011, while back in New Zealand for the 2011 Rugby World Cup, Brooke was inducted into the TVNZ This Is Your Lifewall of fame. His family joined him from England at the Auckland Viaduct for the live show. Special guests included his four brothers, Buck Shelford and Michael Jones. Brooke ran Frances Lodge, a boutique bed and breakfast in Windsor, Berkshire, with his wife. However, it closed when both Brooke and his wife were declared bankrupt in the UK in August 2012. Brooke suffered head trauma in May 2007 while falling out of a taxi in the Spanish town of Elche, though the circumstances are unclear.
Name
Zinzan Brooke's unusual first name has a long history in the Brooke family, though its origins are uncertain. It has been suggested that it may be an anglicised Italian or Albanian name. The name links Brooke's family with another notable New Zealand sporting family, that of cricketer Zin Harris and his sons Chris Z. Harris and Ben Z. Harris, all of whom are distant relatives of the Brookes.
