Club vice-president Duncan Woodhead and life member Val Cullen are pictured planting a commemorative Parrotia persica (Persian ironwood) tree near the ninth hole yesterday.
Centennial committee secretary Joan McLeod said people travelled from as far as Tauranga to attend the event.
A total of 130 people, including all the club's life members, gathered for the formal dinner on Friday night, where longest-serving life members, Val Cullen and Robert Jack, cut the centennial cake.
Heavy rain on Saturday morning meant the decision to open the bar came bit earlier than expected - 11am - but club president Stu Michelle said those couple of hours waiting for the weather to clear were very enjoyable.
"It's been a great weekend. The weather held us back a little bit, but it didn't deter our enthusiasm."
More than 90 people took to the course for the nine-hole game of Canadian foursome on Saturday.
The Centennial trophy was won by Trevor and Susan Duncan, of Lawrence, while Pat Maley and Darryl McKinney won the Jubilee Cup.
Nine holes were played yesterday before the tree was planted on the course to mark the 100th year, followed by a barbecue afternoon tea.
