But the spike he would most like to see is one in player numbers.
The 60-year-old deputy principal at Otago Girls' High School has been involved with volleyball since the mid-1970s.
He is a passionate advocate for the sport and late last month was appointed president of Volleyball New Zealand.
The appointment had been in the pipeline since March but Murley wanted to think about it and discuss it with the school before accepting. In the end, it was an easy decision.
While president is a mostly a ceremonial role, Murley is keen to help the national body wrestle with some of its most pressing problems.
Like a lot of sports, there is a big drop off in player numbers from school to club competitions. There is also a lack of coaches, even at secondary school where the sport is in a relatively healthy position.
"Really, it is about working on getting the club situation sorted and looking at what we can do about getting more coaches," Murley said when asked what issues the sport faced.
"We have a lot of students playing at secondary school level. The secondary schools tournament, which is held in Palmerston North, is one of the larger school tournaments in the country in terms of the number of competitors.
"At that level, it is very healthy. We have a bit of work to do at the club level. We certainly lose players from school to club but that is not just a problem for volleyball."
About 150 teams (1500 pupils) contested the annual national secondary schools tournament, he said, but there were only two senior clubs in Dunedin.
"The men's scene is not as healthy as it should be," he said.
The Vikings club had struggled for numbers over the last few years.
Murley will travel to Wellington this weekend to attend a meeting which aims to address the issue, and in a couple of months he will travel to Anaheim for the world congress.
Worldwide, volleyball is a very popular sport.
Beach volleyball has helped enhance its popularity while also attracting attention away from the indoor game.
In New Zealand, the game struggles to capture the imagination of the public. Olympic coverage should help but Murley is not expecting an influx of interest at club level as the season winds up in August.
However, he is hopeful it will inspire more school children to give the sport a go.
Volleyball was not an option when he went to school. It was not until he started teaching at Otago Girls' in the mid-1970s that he really became involved in the sport. His interest grew from there.
The structure of Volleyball New Zealand has changed over the years but he is a past secretary, a role he held for about eight years in the late 1970s-early 1980s.
More recently, Murley has worked with the match play committee, which is responsible for the rules and regulations for national club competitions.
