"We are not sure yet. We are still deciding," Nina said on the sisters' return to Dunedin yesterday.
"We are kind of on the edge at the moment."
They have spent a lot of time training overseas in Canada over the last few years and were looking forward to being home in Dunedin with their family for the next few months.
The Daniels sisters finished 23rd in the synchronised swimming duet in their first Olympic Games in Beijing.
"It was an amazing experience for us," Nina said.
"It is going to be so memorable. It couldn't have gone any better."
Lisa enjoyed being part of the team in Beijing.
"There was an amazing atmosphere.
"It was one team one spirit and this showed out in all the performances," she said.
"Being part of a team like this makes you want to keep going.
"It's such an amazing feeling to represent the country.
"That makes you want to strive for more."
The sisters have been competing together in synchronised swimming for the last eight years and it has taken them around the world.
They won the bronze medals at the Commonwealth Games in Melbourne in 2006 and are tempted to stay in the sport to compete at New Delhi in 2010.
"We are tempted to try to do better at the next one, but we haven't thought that far ahead yet," Nina said.
The sisters were the fourth Commonwealth team to finish in Beijing behind Canada, Great Britain and Australia.
The Daniels sisters have dominated synchronised swimming in New Zealand since first winning the duet event together in 2000.
