Paul organised the first national mountain bike race in New Zealand - the Karapoti Classic in 1986. The Kennett Bros continued to run this annually until 2002, when they sold the event.
He ran a national mountain bike magazine called Mountain Bike New Zealand Magazine from 1988 - 1990.
In 2001 the Kennett Bros wrote the first edition of Classic New Zealand Mountain Bike Rides, a national guidebook, which became a best seller. They have produced new editions every three years since then.
In 1995 Paul launched the Mountain Bike New Zealand Web, the online home for most New Zealand mountain bikers.
In 1997 they co-organised a round of the UCI World Mountain Bike Cup in Wellington.
In 1998 they started building the Wellington City Council owned Makara Peak Mountain Bike Park, which recently received a national recreation award and a national conservation award.
