The number of Rotorua women terminating their pregnancies has been steadily decreasing since 2009, and is the lowest it has been since 2005.
Waikato District Health Board statistics on the number of Rotorua women terminating a pregnancy shows a steady decline from 246 terminations in 2009 to 164 in 2014.
Rotorua Hospital does not perform abortions.
Local women are referred to the central booking office at Waikato Hospital which organises terminations at Waikato, Tokoroa or Thames hospitals.
The decline in terminations mirrors a decline in live births for Lakes DHB women.
The number of births in the Lakes area peaked in 2009 at 1657, but was only 1322 last year.
New Zealand College of Midwives regional chairwoman Juliette Robinson said the availability of long-term contraception had reduced teen pregnancies, which would contribute to thefigures.
"I don't think there is a difference in whether [pregnancies] are planned or accidental," she said.
"But maybe with the long-term contraception we are able to hopefully stop some of the unplanned, young pregnancies and the repeat young pregnancies - so when they do come in the first time we are able to help them out with long-term contraception."
She had not noticed a decline in pregnancies. "We still feel like we are busy as ever ... [but] we are able to help some of the mums that leave the hospital and get lost in the system - so before they leave the unit they get a Jadelle [a long-acting contraceptive implant]."
Rotovegas Youth Health clinical leader Dr Tania Pinfold previously told the Rotorua Daily Post increased contraceptive options had an impact on lower abortion rates.
"[The] availability of long-acting reversible contraception has added a reliable option to contraceptive choices for women of all ages," she said.
"Jadelle subdermal implants and intrauterine devices can give five years of excellent protection from pregnancy, and they are well tolerated by most.
"The contraceptive pill and Depo Provera are also still common and appropriate choices for some women."
