A swarm of earthquakes within minutes of each other rattled the central North Island this afternoon.

According to GeoNet, the first quake struck at 2.01pm and was magnitude 5.2. It was centred 25km north-east of Porangahau at a depth of 42km.

Minutes later a second quake struck at 2.03pm 5km north of Waipukurau. It was 16km deep and magnitude 3.5.

A third quake, magnitude 4.0, centered in eastern Tararua struck at 2.05pm. It was centred 20km north-east of Porangahau and was at a depth of 36km.

At 2.09pm, a 3.4 magnitude quake struck 20km south-east of Waipukurau at a depth of 37km.

It was followed by a 2.9 magnitude quake at 2.16pm, 10km east of Waipukurau at a depth of 21km.

The quakes were reported to be felt through Hawke's Bay, Manawatu, Wellington and Marlborough regions.

GNS Science duty seismologist Lara Bland said there was nothing to indicate a larger quake was on the way for the area.

The number of aftershocks was normal following a magnitude 5.2 quake, she said.

"This is quite standard as it was a 5.2 and it will generate a few aftershocks.

"Those should drop off in the next two to three days."

The quakes were a reminder people should always remain alert and prepared, she said.

"It's a good chance to check all your kits and supplies.

In the event of a larger quake, people should also be mindful of tsunami risk as it is quite a coastal area, she said. 

Goods fell from some shop shelves in Waipukurau, but no reports of damage had been received by police yet.

Sergeant Ross Gilbert, who has been stationed in the town for the past twelve years, said the quake "was one of the biggest I've felt".

"It was a goodie. We've had a few minor ones in the last few days. Usually we get the rolling sort. This was a shorty sharp shake," he said.

Staff spoken to at the town's New World supermarket said a few items had fallen from shelves "but it wasn't too bad at all given the shake".
