Two local surfers who saw part of last night's skydiving tragedy unfold raced out to sea on a jetski before the sun went down, locating the woman before it got too dark to find her. 

Without their quick thinking, lifeguards may not have been able to find her in the failing light, says Muriwai beach's head lifeguard Glenn Gowthorpe, who was close behind the surfers on his own jetski. 

The woman died after colliding with another skydiver in the air at the west Auckland beach last night. 

The woman, who was part of a large group of skydivers, ended up in the water and died at the scene. The man she collided with, aged in his 20s, received moderate injuries and was taken to Auckland Hospital by helicopter. 

Gowthorpe said there were numerous people watching last night when the accident happened.

"It's not that often that [skydivers] land on the beach so when they do it's quite a spectacle. It was a beautiful night, the sunset was amazing, beautiful conditions and everyone was just looking skywards watching these amazing skydivers come down - but then of course everyone noticed that one of them was off the coast." 

The brightness of the sunset meant he only noticed the person descending when they were about 200m from hitting the water. He said she appeared to be spiralling. It did not appear a normal descent prior to hitting the water. 

He immediately "self-tasked" himself and another lifeguard, Nigel Sorenson, to attempt to rescue her. 

Meanwhile, a local surfer saw the accident happen from his deck, grabbed a friend, hooked his jetski up and went straight down to the beach. 

Gowthorpe said it was "absolutely pivotal".

They had had less than 20 minutes of light left in the day. 

They had performed about five minutes of CPR by the time the lifeguards got there, Gowthorpe said. 

"We assisted them with the patient for a while and at the same time we quickly cut away all the harness and parachute because it was full of water and really heavy." 

The lifeguards then brought the woman back to the beach on the inflatable sled on the back of their jetski. Other lifeguards and the local volunteer fire brigade communicated with them throughout the rescue but they were not aware there was a second injured person until after they returned to the sand. 

The Auckland Westpac Rescue Helicopter touched down on the beach around the same time. 

"It was a really amazing community response," Gowthorpe said. 

"It was so quick - this person had the best response they could have hoped for to give them the best chance of surviving. Unfortunately, that wasn't how the scenario played out." 

He declined to comment on the specifics of what had happened to the woman out of respect for the skydiving community as they grieved. 

"Like lifeguards, they're probably a close community. When someone gets in trouble you trust and rely on each other to help you. And lifeguards, parachutists, military, police probably all operate the same way knowing that someone's got your back." 

He was full of praise for the local surfers who did an "amazing job" getting straight out to sea. 

"It would have been really hard for us to find the patient if they hadn't already got there in the daylight." 

'He was trying his best' 

A Muriwai resident told the Herald he saw the surfers perform CPR for at least 10 minutes. He guessed it was a tow-in jetski, which is normally used to tow surfers onto big waves. 

"I could see one guy pumping up and down for at least 10 minutes. It's just sad - he was obviously trying his best." 

It understood the sky diving plane was also circling over the water. 

He said CPR continued when the lifeguards raced out. They were located about 800m north of Oaia Island, about 900m offshore. 

"The Westpac rescue chopper then arrived and landed on Muriwai Beach." 

The lifeguards brought the woman's body back to the beach. 

The resident captured a photo of the incident after hearing a low-flying plane outside his house, which is on the edge of the cliff above Māori Bay.

Another resident said he noticed what he thought was a sky-diving plane circling out over the water. 

"It was a little unusual and it was rather spectacular so I shot a video. 

"It was circling round and round and dipping down near the ocean from time to time, now I know what it was doing and then a little bit later after dark two helicopters joined the search." 

He said it was sunset when he noticed the plane and for some time it was circulating near Oaia Island. 

He said it was rare to see skydivers near Muriwai. 

"But we have seen them, not in the last couple of years but I have seen them in the past." 

Investigation underway 

Police said they were notified of the incident around 7.43pm. 

"Early indications are that a large group of people were skydiving when two of them have collided in the air. 

"A female diver has sadly gone into the water and died at the scene." 

A Skydive Auckland spokesperson confirmed "the parachutist did take off from Skydive Auckland and we will be releasing a statement in 48 hours".

Westpac Rescue Helicopter pilot James Tayler said they received reports of the incident at around 7.45pm from the Rescue Coordination Centre New Zealand. 

When they arrived, one patient was already at the beach and the other was being transported back to shore on a jetski he said. 

"We went out there ready to winch somebody out of the water but by the time we'd got there, we saw that there was a jetski on its way back to the beach with the second person on the jetski so we landed on the beach to assess what we could do for both patients." 

The patient on the beach was undergoing CPR by emergency services that were already in attendance. 

A St John's spokesperson said one ambulance, one helicopter and a rapid response unit attended the incident. 

They assisted one patient in a moderate condition who was airlifted to Auckland Hospital. 

WorkSafe and the Civil Aviation Authority have been notified. A CAA spokesperson said they will be assigning an investigator. 

A spokesperson from the Transport Accident Investigation Commission also said they were aware of the incident. 

Investigators were gathering further information to inform the chief investigator of accidents, Harald Hendel. A decision to open an inquiry would be made later today the spokesperson said. 

The matter will be referred to the coroner.
